Analysis of the nerve growth activities of protein fractions from the venoms of Agkistrodon halys halys and Echis multisquamatus

The possibility has been shown of obtaining NGFs in the process of isolating coagulant proteinases and other biologically active substances from the venoms of theAgkistrodon halys halys and theEchis multisquamata. Results characterizing the NGFs of both species as basic (weakly basic) proteins with molecular masses of 30.0–40.0 kDa are presented.
