Abstract By configuring the cDNA library for poison gland of lapemis hardwicki and sequencing its DNA, three genes sn12, sn36 and sn160 for coding short-chain neurotoxin are obtained, which are cloned to expression carrier PETTRX by PCR method to modify and to amplity them. The BL21-DE3 is used as expression host. Through IPTG induction, they have the soluble efficient fusion expression in colibacillus. The said genes can greatly increase the pain threshold.
