[ Method] Lescpth5 was amplified by PCR technique, and connected into bait vector pGBKTT. The recombined vector was transformed into yeast competent ceils AH109 and carried out self-activated detection and toxicity detection in the au.xotrephic medium. [ Result] Digestion and sequencing results showed that bait vector pGBKT7-Lescpth5 was suecessfully constructed with correct reading frame. Self-activated activity and toxicity detection results showed that bait vector had no self- activated activity on yeast strain AH109, which also had no toxicity on yeast. [Condusion] Bait vector successfully constructed could be used in yeast two-hybrid system, which laid the foundation for screening of cDNA library in the next step.展开更多
