摘要: 目的 建立共刺激分子配体B7-DC转基因小鼠模型.方法 利用RT-PCR方法从来自小鼠胸腺的mRNA中扩增出B7-DC cDNA,继而将B7-DC基因插入到真核表达载体PEF6/V5-His中得到含B7-DC和V5-His融合蛋白的PEF6-B7-DC/V5-His.注射外源基因PEF6-B7-DCN5-His至FVB小鼠原核,注射胚胎移植到同期发情的假孕受体,所生仔鼠经PCR和Southern-blot检测获得阳性转基因小鼠.结果 共注射移植胚胎87枚,出生小鼠39只,检测出阳性小鼠3只,并稳定遗传至F2代.结论 成功建立了B7-DC转基因小鼠模型.

Abstract: Objective Establishment of B7-DC transgenic mouse model. Method B7-DC cDNA was cloned by RT-PCR from mouse thymus, then it was inserted into PEF6/V5-His vector and get PEF6-B7-DC/V5-His which contain a fuse protein B7-DC-V5-His. The PEF6-B7-DC/V5-His gene was microinjected to the pro nuclear of FVB mouse embryos, then transfer the embryos to the foster mother and get new individuals. Positive founders was confirmed by PCR and Southern. Result Eighty three injected embryos were transferred and 39 offspring mice were obtained, three of them are positive and can be successfully inherited to F2. Conclusion The B7-DC transgenic mice model was established.
