摘要: 采用重叠区扩增法人工合成了大肠杆菌偏爱密码子的猪PR39基因片段,并克隆至pMD18T中,经测序确认正确后,与pETTrx构建了串联表达载体pET-Trx-(PR-39)3,并在大肠杆菌BL21 (DE3)中诱导获得表达。为PR-39的进一步开发与应用打下了基础。

Abstract: Gene RP39 from pig with the partiality of E coli was synthesized by the method of gene splicing by overlap extension. The fragment was cloned into pMD18T and sequenced. Three copies of gene RP-39 were combinated into express vector pET-Trx. Then pETTrx(PR-39)3 was transformed into E coli BL21 (DE3) and RP39 was inducted which established good foundation for the future development.
