In this study, to improve the efficiency of SCNT in Banna Mini-pig Inbred Line (BMI), we obtained the recombinant nucleoplasmin (Npm) by using a prokaryotic expression system and compared the difference on the developmental effects between exogenous Npm and its structural analog, polyglutamic acid (PGA). We chose the pMD18-T vector for Npm expression and transformed E. coli BL21 ...
