METHOD OF PRODUCING BIOSPECIFIC POLYMER SORBENT FOR EXTRACTING PROTEINASE Russian patent published in 2011 - IPC G01N33/53 C12N11/08 

FIELD: chemistry.

SUBSTANCE: in order to produce a biospecific polymer sorbent for extracting proteinase, an aqueous solution undergoes radical polymerisation, where said solution contains 0.1-1.5 wt % ovomucoid from duck egg albumen, acylated with acyl chloride of acrylic or methacrylic acid, 7.0-20.0 wt % hydrophilic monomer consisting of acrylamide, methacrylamide or N-vinylpyrrolidon, and 0.7-15.0 bifunctional cross-linking agent. The hydrophilic monomer is further mixed with N-ethylbromide dimethylaminoethyl methacrylate, taken in amount of 45-55 wt % with respect to weight of the hydrophilic monomer.

EFFECT: addition of N-ethylbromide dimethylaminoethyl methacrylate to the hydrophilic monomer increases efficiency of sorption of proteinase from biological fluids.
