摘要
将组织型纤溶酶原激活剂(t-PA)基因cDNA经多次亚克隆插入到真核表达载体pSVL的SV40启动子和pcDNA3的CMV启动子下游,构建了重组表达质粒pSVL-tPA和pcDNA3-tPA经酶切和Southern杂交鉴定,t-PA基因插向正确,可用于哺乳动物细胞和个体表达系统中表达。
Two expressing plasmids,pSVL-tPA and pcDNA3-tPA,containing the tissue-type plasminogen activator (t-PA) cDNA gene,were constructed by inserting the t-PA cDNA into the downstream of the SV40 promoter and the CMV promoter,respectively.Restriction enzymes digestion and southern bolt demonstrated that t-PA gene had been inserted into right site.The recombinant plasmids could be used as expressing vectors in mammalian cells.
