Objective: We studied the extracted method of informational active components alignment of scorpion

groped the best electrophoresis conditions

determined the molecular mass of informational active components alignment

assured the expressing characteristic of the electrophoretic bands

and set up the bioassay method of informational active components alignment of Scorpion. Method: We extracted scorpion by water and salt fractionation to obtain informational active components alignment

Coomassie brilliant blue method determined its protein content

and SDS-PAGE electrophoretic technique and Alpha Ease FC 4.0.0 software determined its protein molecular weight. Result: The protein content of informational active components alignment was 50.37%. There were ten bands in the informational active components alignment. Ten bands in the SDS-PAGE were 94.162 0

66.400 0

40.357 0
