摘要 目的应用DNA基因芯片对中华骨髓库造血干细胞捐献者血样进行HLA-A、B、DR分型检测,探讨基因芯片应用于中华骨髓库建库的可行性。方法常规提取血样DNA,用国际通用的方法合成PCR引物,对A、B、DR位点进行PCR扩增,电泳检测合格的扩增产物经纯化、点片、固定制成DNA芯片,用荧光标记探针杂交,激光扫描提取数据,专用软件进行分析。结果共得到2 000份分型结果,用目前建库常用的分型试剂对4%随机抽样复核,符合率100%;进行基因频率统计分析,结果与以往资料报告接近。结论HLA基因芯片是一项拥有中国自主知识产权的新技术,高通量、规范化、低价格是其显著优点,比较适合大规模集中化检测的实验室使用。
