摘要 目的 克隆精子表面蛋白P34H基因的编码区,为进一步体外表达P34H蛋白做难备。方法 提取人附睾体部总RNA,并以此为模板,进行反转录PCR获得编码P34H蛋白的基因片段。应用T/A克隆策略,将扩增的P34H基因编码区克隆入T载体,并通过双酶切和DNA测序进行鉴定。同时,以β-actin为内参,进行反转录PCR半定量分析,比较P34H在附睾头部、体部和尾部及睾丸组织中的表达量大小。结果 成功地克隆了P34H基因。将P34H的cDNA序列登录GenBank,登录号为AF515625。反转录PCR半定量分析表明P34H主要在附睾体部表达。结论 克隆的P34H基因可用于构建表达载体,为进一步表达P34H重组蛋白进行有关P34H的基础和应用研究打下了基础。
