摘要
肿瘤坏死因子受体(TNFR)是肿瘤坏死因子(TNF)发挥其生物学作用的关键性物质。利用聚合酶链反应(PCR)技术,扩增并改造55KDTNFRcDNA,成功地扩增出编码可溶性肿瘤坏死因子受体成熟肽的序列,并在该序列的5’端和3’端分别引入EcoRI和HindⅢ识别序列,使之便于与载体重组,为获得亚克隆及在大肠杆菌高效表达奠定基础。
The biological response to TNF is mediated by specific cell surface receptors(TNFR).We use PCR techniques to generate a restriction fragment containing EcoRI site at the 5'end,stop codon,Hind Ⅲ site at the 3'end and cDNA of the extracellular domain (STNFR)of the human 55KD TNF receptor,make STNFR cDNA easy to insert into the vector for subcloning and expression in E.coli.
