The influence of Lamidan preparation on activity preservation with proteolytic enzymes of different origin (papain, trypsin, terrilytin, alkalint protease, protease C) immobilization was studied. Using the SDS- and native electrophoresis methods, the quantitative composition of protease C preparation fractions was investigated, their molecular masses and activity were determined. An effective method of protease C immobilization in biogel lamidan was developed, with quantitative entrapment of enzyme; the textile coatings with prolonged action and 95% retaining of proteolytic activity were obtained.
