方法运用聚合酶链反应-序列特异性引物（PCR-SSP）法，对38例山东汉族人GPP与94例健康对照进行HLA-DQB1等位基因分型。
Methods The distributing frequencies of HLA-DQB1 alleles were detected with polymerase chain reaction-sequence specific primers (PCR-SSP) in 38 GPP patients and 94 healthy subjects from Shandong.
然后分别提取84例拟进行造血干细胞移植病人及家系成员的外周血d NA，采用RSCA和序列特异性引物体外基因扩增(PCR ssp)法平行对照对HLA A基因位点进行分型。
DNA samples of related hematopoietic stem cell transplant donor-recipients were extracted from peripheral blood cells. HLA-A loci were typed both by RSCA and PCR-SSP.
