聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法是一种高效便捷的HLA-DQA1和-DPB1等位基因的准确分型技术,现已扩展并应用于HLA-DRB和-DQB分型。从70株hla -纯合子B细胞株的基因组dna中选择性扩增出HLA-DRB (B1和B3或B4)和DQB (B1和B2)基因的第二外显子。扩增后的dna用限制性内切酶酶切,该酶能识别HLA-DR、-DQ和-Dw同种异体特异性的等位基因变异,然后在聚丙烯酰胺凝胶中进行电泳。在DRB基因中,选取FokI、HinfI、HhaI、HphI、KpnI和SacII,获得的限制性内切片段的20种不同多态性模式与血清学和细胞分型定义的HLA-DR和-Dw型相关。在DQB基因中,FokI、HaeIII、HhaI、RsaI和Sau3AI产生了9种不同的限制性片段多态性模式,与HLA-DQ和-Dw型相关。这种PCR-RFLP方法为在核苷酸水平上准确定义HLA-DR, -DQ和-Dw类型提供了一种简单快速的技术,消除了对放射性同位素以及等位基因特异性寡核苷酸探针的需要。
The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, which we previously reported as an efficient and convenient typing technique for accurate definition of the HLA-DQA1 and -DPB1 alleles, is now extended and applied to HLA-DRB and -DQB typing. The second exon of the HLA-DRB (B1 and B3 or B4) and DQB (B1 and B2) genes was selectively amplified from genomic DNAs of 70 HLA-homozygous B cell lines by PCR. Amplified DNAs were digested with the restriction endonucleases, which can recognize allelic variations specific for HLA-DR, -DQ, and -Dw allospecificities and then subjected to electrophoresis in polyacrylamide gel. Of DRB genes, FokI, HinfI, HhaI, HphI, KpnI and SacII were selected and the 20 different polymorphic patterns of the restriction fragments thus obtained were found to correlate with each HLA-DR and -Dw type defined by serological and cellular typing. Of the DQB genes, FokI, HaeIII, HhaI, RsaI and Sau3AI produced nine different polymorphic patterns of the restriction fragments, correlating with the HLA-DQ and -Dw types. This PCR-RFLP method provides a simple and rapid technique for accurate definition of the HLA-DR, -DQ and -Dw types at the nucleotide level, eliminating the need for radioisotope as well as allele specific oligonucleotide probes.
