Abstract: The cDNA of preprotein and mature protein of rabbit hypophysiscerebri was obtained. The cDNA of mature growth hormone was cloned in pET-3a, then the recombinant expression vector was transformed into E.coli BL21(DE3 plys). The overexpression was performed and the yield was 40% of the total protein.

Key words: rabbit growth hormone, cDNA clone, expression

摘要: 从兔脑下垂体中的mRNA中,利用合成引物逆转录PCR,获得了前体和成熟生长激素的cDNA,成熟生长激素的cDNA克隆在pET-3a表达载体并转化到大肠杆菌BL21(DE3 plys)中,获得了高效表达,表达量达到大肠杆菌总蛋白的40%。
