摘要/Abstract

摘要： 为了研究串联抑制素基因免疫对绵羊孪生的影响，以猪抑制素α(1～32)基因及绵羊补体C3d基因作为选择基因，利用RTPCR技术构建串联抑制素重组质粒，并对60只绵羊进行免疫试验。结果表明：串联抑制素重组质粒pcDNADPPISSDINH和pcDNADPPISSDINHsC3d3构建正确，并在BHK21细胞中获得了分泌型表达。重组质粒pcDNADPPISSDINH和pcDNADPPISSDINHsC3d3免疫绵羊后，双羔率分别为12.5%和25.0%，均与对照组间差异显著（P＜0.05）。串联抑制素重组质粒的成功构建，为抑制素基因疫苗的研制提供了理论依据和技术支撑。

Abstract: To study the effect of tandem inhibin gene immunization on sheep twinning, the recombinant plasmid of tandem inhibin were constructed with inhibin αsubunit (1～32) of pig and complement 3d of sheep by RTPCR, which were used to immunize the sheep. The results showed that the recombinant plasmid, pcDNADPPISSDINH and pcDNADPPISSDINHsC3d3 were constructed successfully. After BHK21 cells were transfected with the recombinant plasmid pcDNADPPISSDINH and pcDNADPPISSDINHsC3d3, secreted expression was obtained. After immunization, the twinning rate of sheep was 12.5% and 25.0%, respectively, which was significantly higher (P＜0.05) than that in the control group. The construction of recombinant plasmid of tandem inhibin gene made the theoretical and technical basis for developing the inhibin gene as vaccine for sheep.
