摘要
用PCR和单链构型多态性(PCR-SSCP)法检查供受者的HLA-DRB-1基因座的多态性的一致性,以此做DRB的基因配型。16例同胞供受者对的DRB-1的PCR-SSCP配型,有6对相合(6/16),10对不合(10/16)。此基因配型结果与其它配型结果比较,说明DRB-1的PCR-SSCP配型在区分同胞供受者对的Ⅱ类抗原多态性上有较高的灵敏度,同时表明此类配型在应用于骨髓移植前检查同胞供者的意义。
he DR_β locus polymorphism of 16 sibling Donor-Re-cipients before BMT was examined by the PCR-SSCP(single-strand conformation polymorphism) technique.Six in 16 D/P pairs were matched and 10 mismatched.When compared the result with that of other matchingmetheds, it was shown that the PCR-SSCP methed hadhigher sensitivity on discrimination of polymophism ofHLA class Ⅱ antigen.
