| pubmed-article:3176589 | pubmed:abstractText | We prepared adsorption immobilized Urease (E.C. 3.5.1.5) with a special method of polymer coating of polystyrene granulate as a matrix, and by subsequent adsorption of two different urease products (AWD Dresden, DDR, 3 U/mg, and Serva, Heidelberg, BRD, 41 U/mg). We obtained the strongest activity (4.0 mumol.g-1.min-1) with immobilisates on polystyrene in comparison with polyvinylchloride, and polyurethane layers, if we used AWD urease (PS, PVC, PUR). By using Serva urease we obtained products with a manyfold of activity (12.8 mumol.g.min-1). This high activity enables us to utilize adsorption immobilized urease for the detoxification of biological fluids. | lld:pubmed |
