摘要 本文从2例葡萄糖6磷酸脱氢酶变异型——台湾客家型[Gd(一)Taiwan-Hakka]患者基因组DNA中,回收经EcoRI完全酶解的3~5kb片段,与载体λgt10插入重组,用SMR10单菌种系统制备包装提取物,对重组的λgt10进行体外包装,构建成二个基因组基因丈库。用^(32)P标记的G6PD cDNA成功地从文库中初选出12个阳性克隆,挑选其中4个阳性克隆再次杂交予以证实,提取其中2个克隆DNA,经限制酶酶切电泳及斑点杂交鉴定,分离到该变异型基因的插入片段,并将其克隆到M13mp19噬菌体。在国内首次完成Gd(一)Taiwan—Hakka型部份基因克隆化分离与鉴定,为DNA序列分析寻找突变部位打下基础。
