Anion Exchange Affinity-Based Controllable Surface Imprinting Synthesis of Ultrathin Imprinted Films for Protein Recognition. Polymers (Basel) 2022; 14:polym14102011. [PMID: 35631893 PMCID: PMC9144501 DOI: 10.3390/polym14102011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 05/10/2022] [Accepted: 05/12/2022] [Indexed: 01/27/2023] Open
Abstract
Anion exchange affinity-based controllable surface imprinting is an effective approach to overcome low imprinting efficiency and high non-specific binding capacity. The template proteins were first immobilized on the anchored tetraalkylammonium groups of the nanoparticles via anion exchange affinity-based interactions, enabling monolayer sorption using a low template concentration. The combined use of surface-initiated photoiniferter-mediated polymerization to precisely control the imprinted film thickness, allowing the formation of homogeneous binding cavities, and the construction of effective binding sites resulted in a low non-specific binding capacity and high imprinting efficiency. The obtained imprinted films benefited from the anion exchange mechanism, exhibiting a higher imprinting factor and faster binding rate than the reference material. Binding tests revealed that the binding strength and selective recognition properties could be tuned to a certain extent by adjusting the NaCl concentration. Additionally, in contrast to the harsh template elution conditions of the covalent immobilization approach, over 80% of the template molecules were readily removed from the imprinted films using supersonic elution with an aqueous mixture of NaCl and HAc. Introducing template immobilization by anion exchange interactions to the synthesis of imprinted materials may provide a new approach for effective biomacromolecular imprinting.

Abstract
A comparative study on weak anion exchangers was performed to investigate the pH dependence, binding strength, particle size distribution, and static and dynamic capacity of the chromatographic resins. The resins tested included: DEAE Sepharose FF, Poros 50 D, Fractogel EMD DEAE (M), MacroPrep DEAE Support, DEAE Ceramic HyperD 20, and Toyopearl DEAE 650 M. Testing was performed with five different model proteins: Anti-FVII mAb (immunoglobulin G), aprotinin, bovine serum albumin (BSA), Lipolase (Novozymes), and myoglobin. Retention showed an expected increasing trend as a function of pH for proteins with low pI. A decrease in retention was observed for some resins at pH 9 likely due to initiation of deprotonation of the weak anion-exchange ligands. Expected particle size distribution was obtained for all resins compared to previous studies. Binding strength to weak anion-exchange resins as a function of ionic strength depends on the specific protein. Binding and elution at low salt concentration may be performed with Toyopearl DEAE 650 M, while binding and elution at high salt concentration may be performed with MacroPrep DEAE Support. Highest binding capacities were generally obtained with Poros 50 D followed by DEAE Ceramic HyperD 20. A general good agreement was obtained between this study and data obtained by the suppliers. Verification of binding strength trends with model proteins was achieved with human growth hormone (hGH) and a hGH variant on the same resins with different elution salts, sodium chloride, sodium hydrogenphosphate, sodium sulphate, and sodium acetate. Static capacity measurements obtained in the traditional experimental set-up were compared with high-throughput screening (HTS) technique experiments with reasonable agreement. Isotherm data obtained from HTS techniques and pulse experiments were successfully combined with mathematical modelling to simulate, develop and optimise the separation process of two model proteins, Lipolase and BSA. The data presented in this paper may be used for selection of resins for testing in process development.

Abstract
Amine-functionalized adsorbents have attracted increasing interest in recent years for heavy metal removal. In this study, diethylenetriamine (DETA) was successfully grafted (through a relatively simple solution reaction) onto poly(glycidyl methacrylate) (PGMA) microgranules to obtain an adsorbent (PGMA-DETA) with a very high content of amine groups and the PGMA-DETA adsorbent was examined for copper ion removal in a series of batch adsorption experiments. It was found that the PGMA-DETA adsorbent achieved excellent adsorption performance in copper ion removal and the adsorption was most effective at pH>3 in the pH range of 1-5 examined. X-ray photoelectron spectroscopy (XPS) revealed that there were different types of amine sites on the surfaces of the PGMA-DETA adsorbent but copper ion adsorption was mainly through forming surface complexes with the neutral amine groups on the adsorbent, resulting in better adsorption performance at a higher solution pH value. The adsorption isotherm data best obeyed the Langmuir-Freundlich model and the adsorption capacity reached 1.5 mmol/g in the case of pH 5 studied. The adsorption process was fast (with adsorption equilibrium time less than 1-4 h) and closely followed the pseudo-second-order kinetic model. Desorption of copper ions from the PGMA-DETA adsorbent was most effectively achieved in a 0.1 M dilute nitric acid solution, with 80% of the desorption being completed within the first 1 min. Consecutive adsorption-desorption experiments showed that the PGMA-DETA adsorbent can be reused almost without any loss in the adsorption capacity.

Abstract
Cibacron Blue F3GA was covalently attached onto monosize poly(glycidyl methacrylate) [poly(GMA)] beads for purification of lysozyme from chicken egg white. Monosize poly(GMA) beads, 1.6 microm in diameter, were produced by a dispersion polymerization technique. The content of epoxy groups on the surface of the poly(GMA) sample determined by the HCl-pyridine method (3.8 mmol/g). Cibacron Blue F3GA loading was 1.73 mmol/g. The monosize beads were characterized by elemental analysis, FTIR and SEM. Adsorption studies were performed under different conditions in a batch system (i.e., medium pH, protein concentration, temperature and ionic strength). Maximum lysozyme adsorption amount of poly(GMA) and poly(GMA)-Cibacron Blue F3GA beads were 1.6 and 591.7 mg/g, respectively. The applicability of two kinetic models including pseudo-first order and pseudo-second order model was estimated on the basis of comparative analysis of the corresponding rate parameters, equilibrium adsorption capacity and correlation coefficients. Results suggest that chemisorption processes could be the rate-limiting step in the adsorption process. It was observed that after 10 adsorption-elution cycle, poly(GMA)-Cibacron Blue F3GA beads can be used without significant loss in lysozyme adsorption capacity. Purification of lysozyme from egg-white was also investigated. Purification of lysozyme was monitored by determining the lysozyme activity using Micrococcus lysodeikticus as substrate. The purity of the eluted lysozyme was analyzed by SDS-PAGE and found to be 88% with recovery about 79%. The specific activity of the eluted lysozyme was high as 43,600 U/mg.

Abstract
A novel superporous agarose (SA) bead characterized by the presence of wide pores has been fabricated by water-in-oil emulsification using solid granules of calcium carbonate as porogenic agent. After cross-linking, the solid granules were removed by dissolving them in hydrochloric acid. Then, the gel was modified with diethylaminoethyl groups to create an anion exchanger, SA-DEAE, for protein adsorption. A homogeneous agarose (HA) bead was also produced and modified with DEAE for comparison. It was found that the porosity of SA-DEAE was about 6% larger than that of HA-DEAE. Moreover, both optical micrographs and confocal laser scanning microscopy (CLSM) of the ion exchangers with adsorbed fluorescein isothiocyanate (FITC) labeled IgG revealed the superporous structure of the SA medium. In addition, the SA-DEAE column had lower backpressure than the HA-DEAE column, confirming the convective flow of mobile phase through the wide pores. Due to the presence of the wide pores, more channels were available for protein transport and, furthermore, more diffusive pores in the agarose network were accessible for the protein approach from different directions. This led to 40% higher protein capacity and two times higher effective pore diffusivity in the SA-DEAE than in HA-DEAE. Moreover, an increase of the efficiency of the SA-DEAE column until a flow rate of 5 cm/min and the independency of the column efficiency at flow rates from 5 to 17.8 cm/min was found, indicating that intraparticle mass transfer was intensified by convective flow at elevated flow rates. Therefore, the chromatographic resolution of IgG and BSA was little affected up to a flow rate of 17.8 cm/min. The results indicate that the SA medium is favorable for high-speed protein chromatography.

Abstract
A novel rigid biporous bead (BiPB) had been fabricated by double emulsification to prepare a (w/o)/w emulsion and a subsequent polymerization. The polymerization of monomers, glycidyl methacrylate and ethylene glycol dimethacrylate, was initiated with benzoin ethyl ether by ultraviolet irradiation. The BiPB with an average diameter of 42.8 microm was characterized to possess two types of pores, i.e., micropores (20-100nm) and superpores (300-4000nm). Its specific surface area was determined to be 41.9m2/g, about 20% smaller than that of a microporous bead (MiPB) (52.1 m2/g). Flow hydrodynamic experiments showed that the BiPB column had smaller backpressure and plate height than those of the MiPB column at a given flow rate. Derivatized with diethylamine (DEA), the static adsorption capacity of the DEA-BiPB was about 7% smaller than that of the DEA-MiPB for BSA (bovine serum albumin). However, frontal analysis demonstrated that the dynamic binding capacity of the DEA-BiPB column was 1.6-2.4 times higher than that of the DEA-MiPB at high flow rate range of 1200-2400cm/h. Moreover, separation of a model protein mixture (myoglobin and BSA) was conducted at mobile phase velocities up to 3000cm/h to compare the performance of the two stationary phases. All the results indicate that the BiPB contains interconnected flowthrough pores and the BiPB column is promising for high-speed protein chromatography.

Abstract
Development of a high-performance stationary phase is an essential demand for high-speed separation of proteins by liquid chromatography. Based on a novel porogenic mode, that is, using superfine granules of calcium carbonate as solid porogen and a mixture of cyclohexanol and dodecanol as liquid porogen, a rigid spherical biporous poly(glycidyl methacrylate-co-ethylene dimethacrylate) matrix has been prepared by radical suspension-polymerization. The epoxide groups of the matrix were modified with diethylamine to afford the ionizable weak base 1-N,N-diethylamino-2-hydeoxypropy functionalities that are required for ion exchange chromatography. Results from scanning electron microscopy and mercury intrusion porosimetry measurements revealed that the matrix contained two families of pores, that is, micropores (10-90 nm) and macropores (180-4000 nm). Furthermore, the biporous medium possesses specific surface area as high as 91.3 m(2)/g. Because of the presence of the macropores that provided convective flow channels for the mobile phase, the dynamic adsorption capacity was found to be as high as 54.6 mg/g wet bead at 300 cm/h, approximately 63.2% of its static capacity. In addition, the column efficiency and dynamic binding capacity decreased only slightly with mobile-phase flow rate in the range of 300-3000 cm/h. These properties made the packed bed with the bidisperse porous matrix suitable for high-speed protein chromatography.

Abstract
This article describes the fabrication and characterization of a novel magnetic poly(glycidyl methacrylate-triallyl isocyanurate-divinylbenzene) matrix containing magnetite colloids. The results showed that the matrix was superparamagnetic and could be separated magnetically from a suspension in a few seconds. Protein adsorption properties of diethylamine-derivatized matrix were characterized with bovine serum albumin (BSA) as a model protein. The static capacity determined by batch adsorption was 79 mg/ml wet matrix. Kinetic study gave an effective diffusivity of BSA of 5.0 x 10(-13) m2/s in the matrix at an initial BSA concentration in the liquid phase of 1.0 mg/ml. Stability of the matrix was confirmed by recycling of the matrix in protein adsorptions.

Abstract
A novel porogenic mode, cooperation of solid granule and solvent, has been introduced to prepare a biporous medium for protein chromatography. The matrix, a ternary copolymer of glycidyl methacrylate, triallylisocyanurate and divinylbenzene, was produced by a simple in situ polymerization with granules of sodium sulfate and cyclohexanol and dodecanol as porogenic agents. Functionalized with diethylamine, the resin (denoted as Resin C) was used as an anion exchanger. The pore structure, specific surface area and chromatographic properties of Resin C were determined and compared with those of the resin with only the solvents as porogen (Resin A) and the resin with only the salt granules as porogen (Resin B). The results indicated that Resin C contained regions of micropores with a maximum at approximately 55 nm and regions of macropores with a distinct maximum near 340 nm, which swelled to about 1 microm in aqueous solution. Compared with Resins A and B, the biporous medium Resin C simultaneously possessed a high specific surface area of 37.2 m2/g and a low back-pressure at mobile phase flow velocity up to 720 cm/h. The result of dynamic porosity showed that mobile phase was able to convectively flow through the macropores in Resin C. The dynamic adsorption capacity of Resin C for bovine serum albumin was as high as 57.0 mg/ml column volume (95.0 mg/g wet resin), basically identical to its static capacity, while that of Resin A was only 1.95 mg/ml column volume (3.12 mg/g wet resin), about 3% that of its static capacity. In addition, the column efficiency of Resin C was comparable to that of Resin B, but much higher than that of Resin A, indicating that the mass transfer behavior of proteins in the column was greatly improved by convective flow through the macropores.

Abstract
A novel continuous bed with high dynamic adsorption capacity for protein has been developed. It is a macroporous poly(glycidyl methacrylate-divinylbenzene-triallylisocyanurate) rod prepared by in situ copolymerization in a chromatographic tube. The bed matrix contained epoxy groups, so diethylaminohydroxypropyl groups were coupled to the matrix, leading to an anion-exchange continuous bed. The component, specific surface area, and the pore structure of the bed matrix were characterized by Fourier transform infrared spectroscopy, BET method and scanning and transmission electron microscopies, respectively. The flow properties, column efficiency and the dynamic adsorption behavior of the bed were studied. The results show that the continuous bed, a ternary copolymer of glycidyl methacrylate (GMA), divinylbenzene (DVB) and triallylisocyanurate (TAIC) with a specific surface area of 56.4 m2/g, consisted of a three-dimensional structure made up of continuous clusters of microspheres (300 nm) and interconnected irregular pores. The rate of mass transfer is enhanced by the convection of the mobile phase through the pores. The dynamic adsorption isotherm of the anion-exchange column for bovine serum albumin was expressed by the Langmuir equation with a dynamic capacity as high as 76.0 mg/g. Moreover, the separation of proteins, i.e. lysozyme, hemoglobin and bovine serum albumin, is little affected by mobile-phase velocity up to 902.5 cm/h; it was completed within 5 min at 902.5 cm/h.
