摘要 目的将基于测序分型(SBT)技术应用于中华骨髓库山东分库建设的探讨。方法使用ABI 3730 xlDNA测序仪,采用SBT直接测序法,对山东地区的3 500份志愿者血液标本进行DNA测序,其中HLAⅠ类基因对第2、3和4外显子双向测序,Ⅱ类基因对第2外显子双向测序,以得到其HLA高分辨分型结果;对部分呈现中分辨分型结果的标本,通过SSSP技术确认。结果 HLA-A、B、DRB1位点分别有48.23%、42.86%和76.91%得到高分辨结果。此3个位点均获得高分结果的比例为15.91%。在随机增选的760例中分辨标本中,659例(86.71%)经SSSP技术后,获得高分辨结果。结论 SBT技术是骨髓分库开展HLA高分辨分型工作的有力工具。
