| Abstract: | Aim:To prepare human recombination P53 protien.Method:Use the recombinant plasmid pT7 7 Hup53 with human p53 cDNA to transform E coli BL21(DE3). During the culture, add into IPTG to induce the transform bacterium to express destination protein P53. And then, with these methods of lysing bacterium and extracted by guanidine hydrochloride extract and purify the destination protein. Result: It was confirmed by protein electrophoresis (SDS PAGE) and immunoblot (Western blot) that the final extract was human P53 protein, and the content was about 0.373 g/L. |
