Moore CP, Pieterson K, DeSousa JM, Toote LE, Wright DW. Characterization and utility of immobilized metal affinity-functionalized cellulose membranes for point-of-care malaria diagnostics. J Chromatogr B Analyt Technol Biomed Life Sci 2021; 1186:123023. [PMID: 34788723 PMCID: PMC8633758 DOI: 10.1016/j.jchromb.2021.123023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 10/29/2021] [Accepted: 10/30/2021] [Indexed: 11/18/2022]
Abstract
Immobilized metal affinity chromatography (IMAC) is a well-established technique for protein separation and purification. IMAC has been previously utilized to capture the malaria biomarker histidine-rich protein 2 (HRP2) from blood, enhancing the sensitivity of field-appropriate diagnostic tools such as lateral flow assays. However, little work has been done to translate this technique to a truly field-usable design. In this study, IMAC-functionalized cellulose membranes are created and characterized fully for future use in applied malaria diagnostics. IMAC-functionalized cellulose membranes were investigated across a range of cellulose substrates, IMAC ligands, and divalent transition metals before use in a capture and elution flowthrough workflow. Following characterization and optimization, it was found that iminodiacetic acid bound to Zn(II) was the most promising ligand-metal pair, with three available coordination sites and a molar loading capacity of 57.7 μmol of metal/cm3 of cellulose. Using these parameters, more than 99% of HRP2 was captured from a large-volume lysed blood sample in a simple flow-through assay and 89% of the captured protein was eluted from the membrane using the chelating compound ethylenediaminetetraacetic acid. Use of this enhancement protocol on an in-house HRP2 lateral flow assay (LFA) yielded a limit of detection of 7 parasites/μL, a 15.8x enhancement factor compared to traditional LFA methods.

Abstract
Dermatopontin (DPT) is an extracellular matrix (ECM) protein with diversified pharmaceutical applications. It plays important role in cell adhesion/migration, angiogenesis and ECM maintenance. The recombinant production of this protein will enable further exploration of its multifaceted functions. In this study, DPT protein has been expressed in Escherichia coli (E.coli) aiming at cost effective recombinant production. The E.coli GJ1158 expression system was transformed with constructed recombinant vector (pRSETA-DPT) and protein was expressed as inclusion bodies on induction with NaCl. The inclusion bodies were solubilised in urea and renaturation of protein was done by on-column refolding procedure in Nickel activated Sepharose column. The refolded Histidine-tagged DPT protein was purified and eluted from column using imidazole and its purity was confirmed by analytical techniques. The biological activity of the protein was confirmed by collagen fibril assay, wound healing assay and Chorioallantoic Membrane (CAM) angiogenesis assay on comparison with standard DPT. The purified DPT was found to enhance the collagen fibrillogenesis process and improved the migration of human endothelial cells. About 73% enhanced wound closure was observed in purified DPT treated endothelial cells as compared to control. The purified DPT also could induce neovascularisation in the CAM model. At this stage, scaling up the production process for DPT with appropriate purity and reproducibility will have a promising commercial edge.

Abstract
We report the development of a fast and accurate fluorescence-based assay for amidine linked to cellulose membranes and Sepharose gel. The assay is founded on the glyoxal reaction, which involves reaction of an amidine group with glyoxal and an aromatic aldehyde, leading to the formation of a fluorophore that can be analyzed and quantified by fluorescence spectroscopy and imaging. While the assay has been reported previously for aromatic amidine estimation in solution phase, here we describe its adaptation and application to amidine linked to diverse forms of solid matrices, particularly benzamidine Sepharose and benzamidine-linked cellulose membranes. These functionalized porous matrices find important application in purification of serine proteases. The efficacy of a protein separation device is determined by, among other factors, the ligand (amidine) density. Hence, a sensitive and reproducible method for amidine quantitation in solid phase is needed. The glyoxal reaction was carried out on microbead-sized Sepharose gel and cellulose membranes. Calibration curves were developed for each phase, which established linearity in the range of 0-0.45 μmol per mL amidine for free amidine in solution, 0-0.45 μmol amidine per mL Sepharose gel, and 0-0.48 μmol per mL cellulose membrane. The assay showed high accuracy (~ 3.4% error), precision (RSD < 2%), and reproducibility. Finally, we show how this fluorescent labeling (glyoxal) method can provide a tool for imaging membranes and ligand distribution through confocal laser scanning microscopy. Graphical abstract.

Abstract
The ligand density critically affects the performance of ion-exchange resins in such measures as the adsorption capacity and transport characteristics. However, for tentacular and other polymer-modified exchangers, the mechanistic basis of the effect of ligand density on performance is not yet fully understood. In this study we map the ionic strength-dependent structural changes in tentacular cation exchangers with variable ligand densities as the basis for subsequent investigation of effects on functional properties. Inverse size-exclusion chromatography (ISEC), scanning electron microscopy (SEM) and small-angle x-ray scattering (SAXS) were used to assess the effect of ionic strength on the pore size and intraparticle architecture of resin variants with different ligand densities. Comparison of ISEC and cryo-SEM results shows a considerable reduction in average pore size with increasing ligand density; these methods also confirm an increase of average pore size at higher ionic strengths. SAXS analysis of ionic strength-dependent conformational changes in the grafted polyelectrolyte layer shows a characteristic ionomer peak at values of the scattering vector q (0.1-0.2Å(-1)) that depend on the ligand density and the ionic strength of the solution. This peak attribution reflects nanoscale changes in the structure of the grafted polyelectrolyte chains that can in turn be responsible for observed pore-size changes in the resins. Finally, salt breakthrough experiments confirm a stronger Donnan exclusion effect on pore accessibility for small ions in the high ligand density variant.

Abstract
It has been proved that the progress of proteomics is mostly determined by the development of advanced and sensitive protein separation technologies. Immobilized metal affinity chromatography (IMAC) is a powerful protein fractionation method used to enrich metal-associated proteins and peptides. In proteomics, IMAC has been widely employed as a prefractionation method to increase the resolution in protein separation. The combination of IMAC with other protein analytical technologies has been successfully utilized to characterize metalloproteome and post-translational modifications. In the near future, newly developed IMAC integrated with other proteomic methods will greatly contribute to the revolution of expression, cell-mapping and structural proteomics.

Abstract
Heterologous proteins are frequently purified by immobilized metal ion affinity chromatography (IMAC) based on their modification with a hexa-histidine affinity tag (His-tag). The terminal His-tag can, however, alter functional properties of the tagged protein. Numerous strategies for the tag removal have been developed including chemical treatment and insertion of protease target sequences in the protein sequence. Instead of using these approaches, we took an advantage of natural interaction of zinc finger domains with metal ions to purify functionally similar retroviral proteins from two different retroviruses. We found that these proteins exhibited significantly different affinities to the immobilized metal ions, despite that both contain the same type of zinc finger motif (i.e., CCHC). While zinc finger proteins may differ in biochemical properties, the multitude of IMAC platforms should allow relatively simple yet specific method for their isolation in native state.

Abstract
Wuchereria bancrofti protein WbSXP-1 was identified and established as a potential candidate for the diagnosis of lymphatic filariasis. For the economic production of rWbSXP-1, osmotically (salt) inducible Escherichia coli GJ1158 was preferred. Cultivation and expression was optimized in 3 L airlift bioreactor (ALB) and was successfully extended to 30 L ALB. Purification of rWbSXP-1 his-tag protein was optimized in technical scale using FPLC and the maximal recovery of rWbSXP-1 with significant level of purity was achieved using the combination of IMAC and gel filtration. Quality criteria for immuno-reactivity of purified rWbSXP-1 were established for diagnostic applications. Enhancement of sensitivity in rapid diagnostic format was optimized to effectively detect weak to strong antibody reactivity in individuals exposed to lymphatic filariasis. Performance of the rapid format during field evaluation was successful. The accelerated stability assessment of the rapid format satisfied the requirements of WHO-cGMP norms. This investigation presents a successful technical scale production and purification of rWbSXP-1 considering the future industrial application and an enhanced rapid flow through antibody assay for the diagnosis of human lymphatic filariasis.

Abstract
Covalent immobilization of glucoamylase on the cellulose-based carrier Granocel was optimized by changing the anchor groups and the methods of activation/immobilization. Binding of the enzyme was via its primary amino groups. It was shown that using carbodiimide and divinyl sulfone for the activation of -COOH and -OH groups on the carrier resulted in the preparations with very low activity. A third method, using pentaethylenehexamine with glutaraldehyde, led to the attachment through a long spacer arm and to the preparations with the highest activity. Further optimization of the carrier's structure consisted of changing pore diameters and amount of functional groups on the carrier surface. The highest activity of bound glucoamylase was obtained by linking the protein via glutaraldehyde on NH(2)-Granocel having high pore size and high number of functional groups. The immobilized enzyme was stable throughout extended storage and possessed higher thermal stability.

Abstract
Terpolymer bead particles (100-350 microm in diameter) were prepared by suspension radical polymerization from methacrylate esters [2,3-epoxypropyl methacrylate (GMA), 2-(2-hydroxyethoxy)ethyl methacrylate (DEGMA) and ethylene dimethacrylate (EDMA)] and subsequently derivatized affording iminodiacetic acid (IDA) chelating sorbents. The sorbents differed in pore volumes (0-0.7 cm3/g) and specific surface areas (0.03-9.8 m2/g) of their matrices as well as in the amounts of immobilized Ni2+-IDA complexes (0.03-1.58 mmol/g). The binding of imidazole was studied by frontal chromatography to evaluate the accessibility of Ni2+-IDA complexes. It was found that an increase in the bonded imidazole content with increasing immobilized Ni2+-IDA concentration was strongly dependent on the matrix morphology. A higher pore volume of the matrix significantly improved the utilizability of Ni2+-IDA complexes for imidazole binding. The performance of the sorbents based on two porous matrices with immobilized Ni2+-IDA concentration (0.1-1.58 mmol/g) differing in pore size distributions was compared in immobilized metal affinity chromatography (IMAC) of monoclonal mouse immunoglobulin IgG1 specific against human choriogonadotropic hormone (GTH-spec IgG1). The results have shown that sorbents based on matrix with large pores (up to 20 microm in diameter) exhibited high protein binding capacities. The GTH-spec IgG1 (Mw=158,000) was eluted from all the sorbents in its native form as was confirmed by MALDI-TOF.

Abstract
Inabilities to process particulate material and to allow the use of high flow rates are limitations of conventional chromatography. Membranes have been suggested as matrix for affinity separation due to advantages such as allowing high flow rates and low-pressure drops. This work evaluated the feasibility of using an iminodiacetic acid linked poly(ethylenevinyl alcohol) membrane in the immobilized metal ion affinity chromatography (IMAC) purification of a human proinsulin(His)(6) of an industrial insulin production process. The screening of metal ions showed Ni(2+) as metal with higher selectivity and capacity among the Cu(2+), Ni(2+), Zn(2+) and Co(2+). The membrane showed to be equivalent to conventional chelating beads in terms of selectivity and had a lower capacity (3.68 mg/g versus 12.26 mg/g). The dynamic adsorption capacity for human proinsulin(His)(6) was unaffected by the mode of operation (dead-end and cross-flow filtration).

Abstract
Macroporous cellulose Granocel was evaluated as a matrix for the immobilization of two lectins Concanavalin A (ConA) (108 kDa) and Wheat Germ Agglutinin (WGA) (36 kDa). Two different methods were employed for the immobilization of the lectins via their protein moieties by a Schiff's bases reaction. One of them results in covalent coupling of the lectin directly to the support and the other gives the attachment through a long spacer arm which benefits the immobilization of voluminous ConA molecules. The adsorbents were characterized by the glycoproteins sorption recording adsorption kinetic data and isotherms. The adsorbents demonstrated high affinity to glycoproteins with a sorption capacity in the column up to 7.4 mg/ml support and a high recovery (up to 93%). The adsorption isotherms of glucose oxidase (GOD) onto ConA adsorbents reveals an adsorption behavior with high and low affinity binding sites. The dissociation constant K(d) of the ligand-sorbate complex is approximately 1 x 10(-6) and 0.4 x 10(-5)M, respectively. It was supposed that the second step is related to the sorption of solvated GOD onto already adsorbed GOD forming sorbate dimers.

Abstract
The purification of proteins from complex cell culture samples is an essential step in proteomic research. Traditional chromatographic methods often require several steps resulting in time consuming and costly procedures. In contrast, protein purification via membrane adsorbers offers the advantage of fast and gentle but still effective isolation. In this work, we present a new method for purification of proteins from crude cell extracts via membrane adsorber based devices. This isolation procedure utilises the membranes favourable pore structure allowing high flow rates without causing high back pressure. Therefore, shear stress to fragile structures is avoided. In addition, mass transfer takes place through convection rather than diffusion, thus allowing very rapid separation processes. Based on this membrane adsorber technology the separation of two model proteins, human serum albumin (HSA) and immungluboline G (IgG) is shown. The isolation of human growth hormone (hGH) from chinese hamster ovary (CHO) cell culture supernatant was performed using a cation exchange membrane. The isolation of the enzyme penicillin acylase from the crude Escherichia coli supernatant was achieved using an anion exchange spin column within one step at a considerable purity. In summary, the membrane adsorber devices have proven to be suitable tools for the purification of proteins from different complex cell culture samples.

Abstract
Immobilized copper(II) affinity chromatography [Cu(II)-immobilized metal affinity chromatography (IMAC)] has been used in proteomics to simplify sample mixtures by selecting histidine-containing peptides from proteolytic digests. This paper examines the specificity of four different support materials with an iminodiacetic acid (IDA) stationary phase in the selection of only histidine-containing peptides in the single step capture-release mode. Three of the sorbents examined were commercially available: HiTrap Chelating HP (agarose), TSK Chelate-5PW, and Poros 20MC. IDA was also immobilized on CIM discs (monolithic glycidylmethacrylate-ethylene dimethacrylate). Tryptic digests of transferrin and beta-galactosidase were used as model samples to evaluate these sorbents. It was found that among the examined matrices, the TSK Chelate-5PW sorbent bound histidine-containing peptides the strongest, while Poros matrix was found to have a high degree of non-specific bindings. Agarose-based columns showed relatively high selectivity and specificity.

Abstract
Purification of recombinant human growth hormone (rhGH) from Chinese hamster ovary (CHO) cell culture supernatant by Gradiflow large-scale electrophoresis is described. Production of rhGH in CHO cells is an alternative to production in Escherichia coli, with the advantage that rhGH is secreted into protein-free production media, facilitating a more simple purification and avoiding resolubilization of inclusion bodies and protein refolding. As an alternative to conventional chromatography, rhGH was purified in a one-step procedure using Gradiflow technology. Clarified culture supernatant containing rhGH was passed through a Gradiflow BF200 and separations were performed over 60 min using three different buffers of varying pH. Using a 50 mM Tris/Hepes buffer at pH 7.5 together with a 50 kDa separation membrane, rhGH was purified to approximately 98% purity with a yield of 90%. This study demonstrates the ability of Gradiflow preparative electrophoresis technology to purify rhGH from mammalian cell culture supernatant in a one-step process with high purity and yield. As the Gradiflow is directly scalable, this study also illustrates the potential for the inclusion of the Gradiflow into bioprocesses for the production of clinical grade rhGH and other therapeutic proteins.

Abstract
Metal-chelating ligand and/or comonomer 2-methacrylolyamidohistidine (MAH) was synthesized by using methacryloyl chloride and L-histidine methyl ester. MAH was characterized by NMR and FTIR. Spherical beads with an average diameter of 75-125 microm were produced by suspension polymerization of methylmethacrylate (MMA) and MAH carried out in an aqueous dispersion medium. Poly(MMA-MAH) beads had a specific surface area of 37.5 m(2)/g. Poly(MMA-MAH) beads were characterized by water uptake studies, FTIR, SEM and elemental analysis. Elemental analysis of MAH for nitrogen was estimated as 34.7 microM/g of polymer. Then, Cu(2+) ions were chelated on the beads. Cu(2+)-chelated beads with a swelling ratio of 38% were used in the adsorption of human-immunoglobulin G (HIgG) from both aqueous solutions and human plasma. The maximum adsorption capacities of the Cu(2+)-chelated beads were found to be 12.2 mg/g at pH 6.5 in phosphate buffer and 15.7 mg/g at pH 7.0 in MOPS. Higher adsorption value was obtained from human plasma (up to 54.3 mg/g) with a purity of 90.7%. The metal-chelate affinity beads allowed one-step separation of HIgG from human plasma. The adsorption-desorption cycle was repeated 10 times using the same beads without noticeable loss in their HIgG adsorption capacity.

Abstract
Recombinant DNA-derived proteins and, in particular, human pituitary hormones, are increasingly used for research, diagnostic and therapeutic purposes. This trend has demanded new synthetic approaches and improved purification techniques. The type and sequence of the purification steps have to be selected in accordance with the cloning and protein expression strategy, the host organism and cellular localization of the protein of interest, with a view to producing the desired product at a required purity, biological activity and acceptable cost. This review article describes and analyzes the main synthetic and purification strategies that have been used for the production of recombinant human growth hormone, prolactin, thyrotropin, luteinizing hormone and follicle-stimulating hormone, giving special consideration to the few published downstream processes utilized by the biotechnology industry. Practically all types of prokaryotic and eukaryotic organisms utilized for this purpose are also reviewed.

Abstract
Since immobilized metal ion affinity chromatography (IMAC) was first introduced, several variants of this method and many other metal affinity-based techniques have been devised. IMAC quickly established itself as a highly reliable purification procedure, showing rapid expansion in the number of preparative and analytical applications while not remaining confined to protein separation. It was soon applied to protein refolding (matrix-assisted refolding), evaluation of protein folding status, protein surface topography studies and biosensor development. In this review, applications in protein processing are described of IMAC as well as other metal affinity-based technologies.

Abstract
Undesired adsorption of host cell proteins poses a big challenge for immobilized metal-ion affinity chromatography (IMAC) purification. In this study, by using His6-tagged protein Fab OPG C11 from Escherichia coli fermentation as a model, we found that the presence of low concentrations of EDTA-Mg2+ in feed streams weakens the adsorption but makes it more specific towards polyhistidine tag. By combining EDTA-Mg2+ treatment and periplasmic extraction, we developed a one-step purification procedure for His6-tagged recombinant Fab OPG C11 using Ni-IDA (iminodiacetic acid) chromatography. This procedure eliminated the buffer exchange step after periplasmic extraction, which is usually required before IMAC in order to remove EDTA. In addition to savings on time and cost, this procedure eliminates undesired adsorption of most host cell proteins thus significantly improves the purity of polyhistidine-tagged recombinant proteins. The strategy of EDTA-Mg2+ treatment may have general application potentials.

Abstract
Ni2+ complexes of the chelating nonporous and porous bead sorbents based on methacrylic esters crosslinked with ethylene dimethacrylate were used in isolation of the horseradish peroxidase-specific immunoglobulin IgG1 from the crude mouse ascitic fluid by immobilized metal ion affinity chromatography (IMAC). Iminodiacetic and aspartic acids were attached to porous poly(glycidyl methacrylate) beads differing in size, morphology and chemical composition. Ethylenediaminetriacetic acid and quinolin-8-ol chelating groups were attached mainly to the surface hydroxyl groups in nonporous poly(diethylene glycol methacrylate) beads through spacers. The latter sorbents exhibited better kinetic characteristics than the former but a very low IgG1 sorption capacity. In a single-step IMAC procedure, the best efficiency in the specific IgG1 purification was obtained with porous sorbents (recovery 92%, purity 73%). Differences in IMAC separations are discussed from the point of view of morphology of polymer beads as well as of the type and concentration of chelating ligands.

Abstract
The search for mechanical supports for biochemically active compounds serving as immunochemical sensors has been the goal of many studies. A new compound in the form of gel fiberglass (GFG) membranes was recently developed as an example of such supports. In this review, these membranes were analyzed with respect to their use for cancer detection. The membranes are prepared from glass fibers covered with oxysilane to provide a sol-gel glass matrix. Derivatization of the support eliminates nonspecific adsorption. A thin layer of protein trapped in the gel glass during its preparation is deposited on the surface of a lattice of glass fibers. The major innovation of the membrane is its large area. External agents percolating through such a membrane contact a maximal number of molecules of the compounds trapped in the sol-gel glass. As a result, this membrane is highly effective. Each GFG column is built from a series of 20 to 30 membranes. The preparation of such columns is relatively simple, requiring only several hours. The capacity of GFG columns is high: the total amount of tumor-associated antigens (TAA) isolated by these columns from the blood of colon cancer patients reached 50% of the total protein and amounted to up to 9-12 mg/ml of serum. The main components of the isolated TAA were the soluble p66 and p51 proteins. A determination of their concentration by HPLC can be used for early cancer detection. Thus, the described method allows the easy and highly effective isolation of TAA and can be used for different goals, including cancer diagnosis. GFG supports have great potential for the isolation of various macromolecules utilizing specific ligands.

Abstract
Immobilized Metal-Affinity Chromatography (IMAC) represents a relatively new separation technique that is primarily appropriate for the purification of proteins with natural surface-exposed histidine residues and for recombinant proteins with engineered histidine tags or histidine clusters. Because the method has gained broad popularity in recent years, the main recent developments in the field of new sorbents, techniques and possible applications are discussed in this article. Advantages of the method and new prospects are described as well as the problems and concerns that appear when the method is to be used for production of pharmaceutical-grade proteins.

Abstract
In order to achieve efficient IMAC (immobilized metal-ion affinity chromatography) purification of tumor necrosis factor alpha (TNF-alpha) and its analogs by a common chromatographic procedure, we tested four histidine-rich affinity tags attached to the N-termini of the trimeric TNF-alpha molecule. Using low cultivation temperature and appropriate protease deficient E. coli strains, it was possible to obtain intact, full-length proteins with NHis2Xa and HisArg tags, which could be purified to over 95% purity in a single step. However, in comparison to model proteins bearing a surface histidine cluster, accumulation of the histidine-tagged proteins in E. coli was significantly reduced, even in protease deficient strains. In addition, the histidine tagged TNF-alpha proteins never displayed good chromatographic behavior, which was otherwise easily achieved with model proteins. Although the most popular hexa-histidine tag is generally recognized as very convenient for single step isolation of monomeric proteins, our results with trimeric TNF-alpha indicate that oligomeric proteins may require further optimization of the tag, with respect to its length, composition, and location. Histidines, relatively rigidly inserted in the structure, as in our model proteins, display superior chromatographic characteristics vis a vis flexible tags with the same total number of histidines.

Abstract
The development of mechanical supports for biochemically active compounds serving as immunochemical sensors has been the goal of many studies. A new compound in the form of gel fiberglass (GFG) membranes was recently developed as an example of such supports. These membranes prepared from glass fibers covered with oxysilanes to create a matrix 'gel fiberglass' (R. Zusman, USA Patent #08/112,087, 1993) were used to prepare affinity chromatography columns for the isolation of soluble p53 protein from the serum of cancer patients. A thin layer of protein, trapped in gel glass during its preparation, was deposited on a lattice of glass fibers. Derivatization of the support eliminated nonspecific adsorption of proteins. Under such conditions, external agents percolating through a membrane may contact a maximum number of protein molecules trapped in the gel glass. The membranes are very stable, and can be stored in dry conditions for several months at room temperature. Affinity chromatography columns were prepared from the GFG membranes and used to isolate various proteins, including tumor-associated antigens (TAA). The capacity of the columns was calculated as the amount of protein (mg ml(-1)) isolated from TAA-containing solution, and amounted to up to 9 mg ml(-1) of serum in colon cancer patients. The cytoplasmic p53 protein was one of the main components of TAA isolated in our experiments. Its concentration was determined by HPLC. This protein was isolated from the serum of cancer patients in the highest concentration yet reported, up to 5 mg ml(-1). The described method allows an easy and highly effective isolation of TAA and can be used for important goals including cancer diagnosis.
