ENZYMATIC PROPERTIES OF BOVINE PLASMIN PREPARATIONS; EVIDENCE FOR SIMILARITY TO BUT NON-IDENTITY WITH TRYPSIN

Abstract

The enzymatic properties of both chloroform-only activated and trypsin-chloroform activated bovine fibrinolysin (plasmin) have been studied and compared with trypsin. These studies accentuate the remarkable similarity between plasmin and trypsin but definitely establish their distinct individuality and the validity of the procedure using trypsin to activate plasminogen to plasmin.
