摘要
The restriction fragnent length polymorphisms （RFLPs） of HLA class I genes in 104 unrelated healthy Chinese individuals were analyzed with Southern blot assay. The DNAs from peripheral blood leucocytes were digested with EcoRI, EcoRV and XbaI respectively, and hybridized with <sup>32</sup>P-labeled HLA class I probe （ 1.4Kb, B7 cDNA ）. The results showed that 3 EcoRI fragments （13.7, 8.1 and 5.2 Kb ）, 3 EcoR V fragments （11.3, 7.8 and 4.1 Kb） and 7 Xbal fragmnents （21.9, 19.2, 16.3, 6.0, 3.8, 1.8 and 1.5 Kb） were polymorphic. Ten of the fragments were found to be correlated significantly with the serologically de fined antigen specificities. The significance of this kind of correlation is discussed.
