Alginate Beads Encapsulation Matrix for Urease and Polyethyleneglycol-Urease
Artificial Cells, Blood Substitutes, and Biotechnology, 2007 Urease was immobilized activated PEG-5000 and encapsulated urease and PEG modified urease within alginate beads. Encapsulated urease and PEG-urease were thoroughly characterized for pH, temperature and stabilities and these properties were compared with free and PEG modified enzyme.
