By Q-sepharose column ion-exchange chromatography, alkyl-sepharose column hydrophobic chromatography the purified fibrinogenolytic enzyme was obtained from Agkistrodon halys halys venom. It is a single peptide-chain with molecular weight about 28 kDa. It was founded that this enzyme cleaved A alpha-chain of fibrinogen, pH-optimum was determined in the range of 7.
