[Effect of the Hydrogel Carrier Structure on the Activity of Immobilized Trypsin]. 2015

L I Valuev, and I L Valuev, and L V Vanchugova, and T A Valueva

The dependence of the activity of trypsin immobilized in polyacrylamide hydrogel on the hydrogel swelling ratio, the size distribution of its pores, and the means of enzyme binding has been studied. It has been shown that the most favorable conditions for immobilized trypsin are provided upon its binding to hydrogel via trypsin macromonomer copolymerization with acrylamide and a linking agent in the presence of a modifier that limits polymer chain growth.

UI MeSH Term Description Entries
D000180 Acrylic Resins Polymers of high molecular weight which are derived from acrylic acid, methacrylic acid or other related compounds and are capable of being molded and then hardened to form useful components. Acrylic Resin,Resin, Acrylic,Resins, Acrylic
D014357 Trypsin A serine endopeptidase that is formed from TRYPSINOGEN in the pancreas. It is converted into its active form by ENTEROPEPTIDASE in the small intestine. It catalyzes hydrolysis of the carboxyl group of either arginine or lysine. EC 3.4.21.4. Tripcellim,Trypure,beta-Trypsin,beta Trypsin
D055767 Immobilized Proteins Proteins that are chemically bound to a substrate material which renders their location fixed. The immobilization of proteins allows their use in chemical reactions without being diluted by solvent. Proteins, Immobilized
D058105 Polymerization Chemical reaction in which monomeric components are combined to form POLYMERS (e.g., POLYMETHYLMETHACRYLATE). Polymerizations
D020106 Acrylamide A colorless, odorless, highly water soluble vinyl monomer formed from the hydration of acrylonitrile. It is primarily used in research laboratories for electrophoresis, chromatography, and electron microscopy and in the sewage and wastewater treatment industries.
D020136 Hydrogel, Polyethylene Glycol Dimethacrylate A network of cross-linked hydrophilic macromolecules used in biomedical applications fabricated by photopolymerization of polyethylene glycol dimethacrylate. Its general formulae is C3H5C(O)(OCH2CH2)nOC(O)C3H5 where n denotes a number of average polyglycol (OCH2CH2) repeats.
