[Identification of seven snake-drugs by iso-electric point]

This paper deals with the identification of seven snake-drugs by means of iso-electric point of protein. The experimental results show that different species of snake-drugs have different iso-electric points. The experimental data are accurate and easily reproducible (CV less than 0.5%). The difference of the averages of iso-electric points of the seven snake-drugs (P less than 0.01%) is extremely significant and thus provides a scientific criterion for the identification of peeled or powdered snake-drugs.
