摘要
应用DNA重组技术将编码人碱性成纤维细胞生长因子(bbFGF)的基因克隆至原核高效表达质粒pBV_(221)的启动子下游。SDS-SAGE、ELISA和NTT活性监测结果表明:该重组质粒pBV-hbFGF在大肠杆菌DH5α中,经42℃诱导后,可表达出有较高生物活性的hbFGF。
The cDNA sequence coding for human basic fibroblast growth factor (hbFGF) has been cloned downstream of a PR PL promoter of the expression plasmid pBV221 by DNA recombinant technique. Expression of this recombinant plasmid pBV-hbFGF in Escherichia Coli DH 5a by 42 C heat induction yielded hbFGF with high biological activity, according to the SDS-PAGE analysis, EL1SA and MTT bioassay method.
