Abstract:
Saturation mutagenesis is a powerful tool in protein engineering. Even though QuikChange site-directed mutagenesis method is dominantly used in laboratories, it could not be successfully applied to the generation of a focused mutant library of human glutathione transferase A2-2. In the present study, we further developed an improved versatile dual-tube approach of randomizing difficult-to-amplify targets, exhibiting significant improvement towards equal distribution of nucleotides at randomized sites compared to other published methods.
