Abstract
The cDNA of BmK IT-AP, an excitatory insect toxin from the scorpion Buthus martensi Karsch that has an analgesic effect on mammalian cells, was expressed in E. coli in the form of an inclusion body. Following denaturation and reduction, the recombinant protein was renatured and purified by liquid chromatography. The authenticity of the recombinant product was confirmed by bioassay and its electrophysiological effect on insect sodium channel.
