We manufactured a pGEX6P2 derived GST PR CagA(C3) His vector and expressed it because of v Src in E. coli. After refinement and cleavage of the GST tag, pagerank CagA(C3) His was obtained. the degree of tyrosine phosphorylation of PR CagA(C3) His by v Src was then vary that of CagA(C3) the dog’s by v […]
