Conclusion : by restriction enzyme secting, ligating, transforming, restriction enzyme analysis, and final dna sequencing, the pbd-i and pbd-ii gene were proved to be recombinated with the expression vector and the recombinated vector ppd-1 and ppd2 were transformed successfully 結(jié)論:經(jīng)過酶切、連結(jié),構(gòu)建成重組質(zhì)粒ppd上、ppd上,再經(jīng)轉(zhuǎn)化、抽提質(zhì)粒及酶切分析,最后經(jīng)dna測序證實,rticr擴增的pbdi、pbd11基因與piflpdt”xsi表達(dá)載體構(gòu)建成功。
