摘 要:目的:构建小鼠生精相关基因Vad1.2表达载体并进行鉴定。方法: 将小鼠睾丸组织中Vad1.2转录本进行RT-PCR扩增,通过DNA重组技术将其插入克隆载体pET15b中,将表达载体转化入大肠杆菌BL21(DE3)RIL感受态细胞,提取重组质粒并通过酶切及DNA测序进行鉴定。结果:随机挑取的克隆经双酶切鉴定,证实Vad1.2表达载体构建成功,插入基因序列正确。结论: 成功构建了小鼠Vad1.2基因表达载体,为Vad1.2基因的进一步研究奠定了实验基础。

Abstract:Objective: To construct and characterize the Vad1.2 expression vector related to spermatogenesis in mice. Methods: Vad1.2 transcript was amplified from mouse testis by RT-PCR. The amplified product was inserted into pET15b vector. Then the Vad1.2 over-expression vector was transformed into E. coli BL21 (DE3) RIL competent cells and identified by endonuclease digestion and DNA sequencing ......
