摘要 目的 克隆人睾丸肿瘤抗原MAGE- C2基因的c DNA,并在大肠杆菌中进行表达与纯化,以便为研究其生物学功能及制备肿瘤疫苗奠定基础。方法 从人胶质瘤细胞系BT- 32 5中提取总RNA,用RT- PCR从中扩增出MAGE- C2的c DNA片段,将MAGE- C2的c DNA片段插入载体p GEM- T easy中,经全自动序列分析仪测序正确后,再克隆至表达载体p GEX- 4 T- 2中,构建重组表达载体p GEX- 4 T- 2 - MAGE- C2 ,并转化大肠杆菌,用IPTG进行诱导后,收集细菌,菌体裂解后,利用GST亲和层析柱对表达蛋白进行纯化,并进行SDS- PAGE及Western- blot检测。结果 从人胶质瘤细胞系BT- 32 5中克隆到长4 0 0 bp的MAGE- C2的c DNA,测序正确;经Xho I和Bam H I酶切鉴定证实,MAGE- C2 c DNA成功克隆到表达载体p GEX- 4 T- 2中;构建的表达载体p GEX- 4 T- 2 - MAGE- C2在大肠杆菌中表达出Mr4 10 0 0的融合蛋白,经谷胱甘肽(GST)亲和层析后的融合蛋白纯度达到90 % ,该融合蛋白具有MAGE- C2抗原特性。结论 成功地克隆并表达了MAGE- C2 c DNA,并对融合蛋白进行了初步纯化,为大规模获得MAGE- C2抗原创造了条件。
