Abstract
A variety of organic nanomaterials and organic polymers are used for enzyme immobilization to increase enzymes stability and reusability. In this study, the effects of the immobilization of enzymes on organic and organic-inorganic hybrid nano-supports are compared. Immobilization of enzymes on organic support nanomaterials was reported to significantly improve thermal, pH and storage stability, acting also as a protection against metal ions inhibitory effects. In particular, the effects of enzyme immobilization on reusability, physical, kinetic and thermodynamic parameters were considered. Due to their biocompatibility with low health risks, organic support nanomaterials represent a good choice for the immobilization of enzymes. Organic nanomaterials, and especially organic-inorganic hybrids, can significantly improve the kinetic and thermodynamic parameters of immobilized enzymes compared to macroscopic supports. Moreover, organic nanomaterials are more environment friendly for medical applications, such as prodrug carriers and biosensors. Overall, organic hybrid nanomaterials are receiving increasing attention as novel nano-supports for enzyme immobilization and will be used extensively.

Abstract
Enzymes are excellent catalysts in many applications due to their biocompatibility, low energy consumption, unique selectivity, and mild reaction condition. However, some disadvantages limit the usage of enzymes in end uses, such as low stabilities and difficult recovery. In order to overcome these disadvantages, enzyme immobilization was developed. Among various kinds of substrates for attaching enzyme, cellulose and its derivatives are one of the ideal matrixes because they are low cost, nontoxic, renewable, biodegradable, and biocompatible. In this review, we summarize recent progress in the research of enzyme immobilization on cellulose matrixes.

Abstract
We have prepared a novel magnetic metal-chelate adsorbent utilizing methacryloylamidoglutamic acid (MAGA) as a metal-chelating ligand. MAGA was synthesized by using methacryloyl chloride and L-glutamic acid dihydrochloride. Magnetic beads with an average diameter of 50-100 microm were produced by suspension polymerization of 2-hydroxyethyl methacrylate (HEMA) and MAGA in the presence of Fe3O4 particles carried out in an aqueous dispersion medium. Magnetic beads were charged with the Cu2+ ions directly via MAGA for the adsorption of cytochrome c (cyt c) from aqueous solutions. The maximum cyt c adsorption capacity of the Cu2+-chelated beads (0.86 mmol/g Cu2+ loading) was found to be 37 mg/g at pH 8.0 in phosphate buffer. Cyt c adsorption on the poly(HEMA-MAGA) beads was 15.4 mg/g. Cu2+ charging increased the cyt c adsorption significantly (37 mg/g). Cyt c adsorption decreased with increasing temperature. Cyt c molecules could be adsorbed and desorbed five times with these adsorbents without noticeable loss in their cyt c adsorption capacity. The resulting magnetic chelator beads posses excellent long term storage stability.

Abstract
Protein immobilization on surfaces is of great importance in numerous applications in biology and biophysics. The key for the success of all these applications relies on the immobilization technique employed to attach the protein to the corresponding surface. Protein immobilization can be based on covalent or noncovalent interaction of the molecule with the surface. Noncovalent interactions include hydrophobic interactions, hydrogen bonding, van der Waals forces, electrostatic forces, or physical adsorption. However, since these interactions are weak, the molecules can get denatured or dislodged, thus causing loss of signal. They also result in random attachment of the protein to the surface. Site–specific covalent attachment of proteins onto surfaces, on the other hand, leads to molecules being arranged in a definite, orderly fashion and uses spacers and linkers to help minimize steric hindrances between the protein and the surface. This work reviews in detail some of the methods most commonly used as well as the latest developments for the site-specific covalent attachment of protein to solid surfaces.

Abstract
The site-specific modification of proteins is expected to be an important capability for the synthesis of bioconjugates in the future. However, the traditional repertoire of reactions available for the direct modification of proteins suffers from lack of specificity, necessitating costly downstream processing to isolate the specific species of interest. (1) Here, we use a well-established, glycan-specific chemistry to PEGylate model glycoproteins, each containing a unique reactive GalNAc attached to a specifically engineered threonine residue. By engineering E. coli to execute the initial steps of human, mucin-type O-glycosylation, we were able to obtain homogeneous site-specifically modified glycoproteins with fully human glycan linkages. Two mucin-based reporters as well as several fusion proteins containing eight-amino-acid GalNAc-T recognition sequences were glycosylated in this engineered glycocompetent strain of E. coli. The use of one sequence in particular, PPPTSGPT, resulted in site-specific glycan occupancy of approximately 69% at the engineered threonine. The GalNAc present on the purified glycoprotein was oxidized by galactose oxidase and then coupled to hydroxylamine functionalized 20 kDa PEG in the presence of aniline. The glycoprotein could be converted to the PEGylated product at approximately 85% yield and >98% purity as determined by comparison to the products of control reactions.

Abstract
The goal of this paper is to introduce a universal method for quantitative control of the particle size of magnetic cellulose microspheres (MCMS) and to produce an optimal antibody absorption capability as an aid in the research of new applications of MCMS in immunomagnetic capture. In this study, "the smallest critical size theory" (TSCS) was proposed, tested, and confirmed by IgG-carrying capability measurements, magnetic response analysis, immunomagnetic capture, and PCR identification of bacteria. A Gaussian expression was proposed and used to guide the preparation of MCMS of the smallest critical size (SCS). The results showed that the diameter of the SCS of MCMS in this study was 5.82 mum, while the IgG absorption capability of the MCMS with SCS was 186.8 mg/mL. In addition, its high sensitivity and the efficiency of immunomagnetic capture of Salmonella bacteria exhibited another new application for MCMS.

Abstract
The presented work introduces a novel method to immobilize enzymes either purified or directly out of a crude extract onto magnetic particles in the micrometer range. This method is based on the creation of a fusion protein consisting of the enzyme of choice and a mutant dehalogenase. The dehalogenase gene is commercially available from the company Promega under the name HaloTag(TM). When the fusion protein is contacted with magnetic beads having chemically synthesized, chloroalkane ligands on their surface, the dehalogenase and the ligand undergo a covalent coupling leading to stable and spatially defined immobilization. The principle was proved with a lipase fused to the HaloTag(TM) gene and magnetic poly(methyl)methacrylate beads as carriers. The solubility of the tagged lipase was strongly increased by fusion of the malE gene at the N-terminal end of the HaloTag(TM) lipase gene. This tripartite protein was purified on amylose resin and used for immobilization. About 13 µg protein could be immobilized per 1 mg of beads within a few minutes. Due to the defined binding site, no activity loss was observed in the course of the immobilization. The resulting enzyme carrier was tested with the same beads up to six times for lipase activity over a storage period of 36 days at 8 °C. No loss of activity was found during this time.

Abstract
The main objective of this study is to develop and evaluate the immobilization of Staphylococcal Protein A on magnetic cellulose microspheres (SPA-MCMS) for immunological capture of IgG. After cloning, expression and separation, SPA was immobilized onto MCMS to prepare a magnetic affinity media subject to the purification of IgGs. The binding capacity, binding time, leakage of SPA and its reproducibility were optimized to improve the binding efficiency with an appropriate amount and recovery of IgG. Rabbit IgG was successfully purified from serum in a single-step by SPA-MCMS with an overall recovery of 73.18% and purity of 90.27%. Therefore, this study effectively illustrated the advantages of magnetic microcarriers for rapid and efficient purification of antibodies. The separation media shows a high potential for the future development of affinity isolation and immunodiagnostic application.

Abstract
We have developed a novel method for immobilizing antibodies onto magnetic cellulose microspheres (MCMS) using a cellulose binding domain-protein A (CBD-ProA) linkage. Biospecific connection between antibodies and MCMS exhibited significant advantages compared to chemical coupling, including convenient and simple preparation, elimination of toxic compounds, and highly efficient antibody utilization. To evaluate the application of this method, interferon alpha-2b (IFN alpha-2b) was chosen as a model target for detailed analysis of method parameters, such as protein adsorption, antibody efficiency, and reproducibility of the matrix. After optimization and characterization, IFN alpha-2b was successfully purified from crude cell lysate in a single step by cross-linked anti-IFN alpha-2b IgG protein A-CBD-MCMS, purifying 106.1 microg IFN alpha-2b/mL matrix, corresponding to a 13-fold increase over the chemical coupling method. Size-exclusion HPLC identified that the IFN alpha-2b isolated by this method had an overall purity of 95.5%, while immunological and biological assays showed an activity recovery of 91.9% and specific antiviral activity of 2.67 x 10(8)IU/mg. Overall, this study effectively illustrates the favorable qualities of this immobilization method with precisely defined properties that provide an attractive strategy for developing large-scale purification suitable for targeting compounds in highly complex samples.

Abstract
Magnetic poly(ethylene glycol dimethacrylate-N-methacryloyl-(L)-histidine methyl ester) [mag-poly(EGDMA-MAH) beads, 50-100 microm in diameter, were produced by suspension polymerization for affinity depletion of immunoglobulin G (IgG) from human serum. Cu2+ ions were complexed directly via MAH groups (Cu2+ loading: 4.1 micromol/g). IgG depletion studies were performed by magnetically stabilized fluidized bed column. Acetate, Tris-HCl, MES and phosphate buffers all allow adsorption of similar quantities of IgG (27.3-45.6 mg/g). MOPS and HEPES allow higher adsorption quantities (79.6 mg/g and 74.1mg/g, respectively). Maximum adsorption capacities in MOPS buffer were 46.8 mg/g for mag-poly(EGDMA-MAH) and 102.1mg/g for Cu2+ chelated mag-poly(EGDMA-MAH) beads. The adsorption capacity decreased drastically from 102.1mg/g to 30.7 mg/g with the increase of the flow rate from 0.2 ml/min to 3.5 ml/min. The elution studies were performed by 1.0M NaCl. The elution results demonstrated that the adsorption of IgG to the adsorbent was reversible. To test the efficiency of IgG depletion from human serum, proteins in the serum and eluted portion were analyzed by two-dimensional gel electrophoresis. The depletion efficiency for IgG was above 99.4%. Eluted proteins include mainly IgG, and a small number of non-albumin proteins such as apo-lipoprotein A1, sero-transferrin, haptoglobulin and alpha1-antitrypsin. When anti-HSA-sepharose adsorbent is used together with our metal-chelated mag-beads, IgG and HSA can be depleted in a single step.

Abstract
In this work we use micro-size poly(methyl methacrylate)/acrylaldehyde microspheres as a support for pepsin immobilization. The aldehyde groups on the microspheres offer a very simple, mild and firm combination for enzyme immobilization. The amount of enzyme we can bind to this support reaches 82 mg/g, which is much higher than for other supports (mostly less than 10 mg/g). Compared to free enzyme, the Km of immobilized enzyme is increased, whereas the Vmax is decreased. Further, the Vmax/Km value for immobilized pepsin is about 50% of the value for free enzyme. This is better than values reported previously, generally lower than 35%. The optimum temperature shifts from 43 degrees C for free pepsin to 47 degrees C. However, the optimum pH does not change between free and immobilized enzyme. This improved resistance of the immobilized enzyme towards changes in temperature and pH also shows that the aldehyde modified poly(methyl methacrylate)/acrylaldehyde microspheres can be a valuable support for pepsin immobilization.

Abstract
The electrochemistry of some copper-containing proteins and enzymes, viz. azurin, galactose oxidase, tyrosinase (catechol oxidase), and the "blue" multicopper oxidases (ascorbate oxidase, bilirubin oxidase, ceruloplasmin, laccase) is reviewed and discussed in conjunction with their basic biochemical and structural characteristics. It is shown that long-range electron transfer between these enzymes and electrodes can be established, and the mechanistic schemes of the DET processes are proposed.

Abstract
Background Aluminum has recently been recognized as a causative agent in dialysis encephalopathy, osteodystrophy, and microcytic anemia occurring in patients with chronic renal failure who undergo long-term hemodialysis. Only a small amount of Al(III) in dialysis solutions may give rise to these disorders. Methods Magnetic poly(2-hydroxyethyl methacrylate) (mPHEMA) beads in the size range of 80–120 μm were produced by free radical co-polymerization of HEMA and ethylene dimethacrylate (EDMA) in the presence of magnetite particles (Fe3O4). Then, metal complexing ligand alizarin yellow was covalently attached onto mPHEMA beads. Alizarin yellow loading was 208 μmol/g. These beads were used for the removal of Al(III) ions from tap and dialysis water in a magnetically stabilized fluidized bed. Results Al(III) adsorption capacity of the beads decreased with an increase in the flow-rate. The maximum Al(III) adsorption was observed at pH 5.0. Comparison of batch and magnetically stabilized fluidized bed (MSFB) maximum capacities determined using Langmuir isotherms showed that dynamic capacity (17.5 mg/g) was somewhat higher than the batch capacity (11.8 mg/g). The dissociation constants for Al(III) were determined using the Langmuir isotherm equation to be 27.3 mM (MSFB) and 6.7 mM (batch system), indicating medium affinity, which was typical for pseudospecific affinity ligands. Al(III) ions could be repeatedly adsorbed and desorbed with these beads without noticeable loss in their Al(III) adsorption capacity. Conclusions Adsorption of Al(III) demonstrate the affinity of magnetic dye-affinity beads. The MSFB experiments allowed us to conclude that this inexpensive sorbent system may be an important alternative to the existing adsorbents in the removal of aluminium.

Abstract
The newly developed immobilized enzyme reactors (IMERs) with proteolytic enzymes chymotrypsin, trypsin or papain were used for specific fragmentation of high molecular-mass and heterogeneous glycoproteins immunoglobulin G (IgG) and crystallizable fragment of IgG (Fc). The efficiency of splitting or digestion were controlled by RP-HPLC. The specificity of digestion by trypsin reactor was controlled by MS. IMERs (trypsin immobilized on magnetic microparticles focused in a channel of magnetically active microfluidic device) was used for digestion of the whole IgG molecule. The sufficient conditions for IgG digestion in microfluidic device (flow rate, ratio S:E, pH, temperature) were optimized. It was confirmed that the combination of IMERs with microfluidic device enables efficient digestion of highly heterogeneous glycoproteins such as IgG in extremely short time and minimal reaction volume.
