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
