我们采用序列特异性引物聚合酶链反应（ＰＣＲＳＳＰ）技术对脐血ＨＬＡＤＲ、ＤＱ抗原进行分型，并与单克隆抗体（单抗）法进行比较，报告如下。材料和方法１ 样本 脐血５０份，其中来源于足月产妇３０份（其中２０份为随机抽样脐血；１０例为地中海贫血家族同胞脐血）
We use sequence-specific primer polymerase chain reaction (PCR SSP) technology for cord blood HLA DR, DQ antigen typing, and monoclonal antibody (mAb) were compared, reported as follows. Materials and methods 1 samples of 50 cases of umbilical cord blood, which comes from 30 full-term pregnant women (of which 20 were randomly sampled cord blood; 10 cases of thalassemia relatives cord blood)
