摘要
为探索一种可靠性和灵敏性高的HLAⅡ类基因的配型方法,根据Olerup提出的16个特异性引物序列,用多聚酶链反应-序列特异性引物(PCR-SSP)方法,对DQA_1基因位点的多态性进行检测和分型,并与多聚酶链反应-序列特异性寡核苷酸探针杂交(PCR-SSOPH)及多聚酶链反应-单链构型多态性(PCR-SSCP)检测结果进行比较,获得了一致的分型结果。PCR-SSP可分辨出DQA_1位点的纯合体和杂合体等位基因,并能检测出单一碱基的点突变;它将PCR扩增和检测两个步骤合并为一次完成,操作更简便、快速。并已将PCR-SSP方法成功地用于15对异基因骨髓移植的供、受者的分型。PCR-SSP作为基因分型的有效技术,可为骨髓来源提供直接的科学依据。
To explore a reliable,sensitive typing method for HLA gene,polymorphism of DQA1 gene locus was detected and typed by means of polymerase chain reaction-sequence specific primer(PCR-SSP)technique and the results were compared with those of PCR-sequence specific oligonucleotide primer hybridization and PCR-single strand conformation polymorphism.The results showed that PCR-SSP could detect homozygous and heterozygous alleles of DQA1 locus and single base point mutation,and proved to be simple,rapid and suitable for routine clinical application.
