人血痕ORM、Pi、AHSG和GC同步等电聚焦分型

作者在国内外首次建立了血清类粘蛋白、α1－抗胰蛋白酶、α2－HS－糖蛋白和型特异性成份等四种遗传标记同步等电聚焦免疫酶放大分型方法。累计个人识别机率为0．9878，非父排除率为0．6648，是国内外已报道同步电泳分型方法中鉴别能力最高的。本法可对稀释度为1／100的血清进行分型。对于室温保存四周的血痕盯全部正确分型。除Pi外，ORM、AHSG和GC三种遗传标记至少在24周之内皆可正确分型。

SIMULTANEOUS PHENOTYPING OF ORM, PI, AHSG AND GC IN HUMAN BLOODSTAINS USING PAGE IEF IMMUNOASSAY

A PAGE IEF immunoassay was established to detect the ORM, Pi, AHSG and GC phenotypes slmultaneously in human bloodstains. The cumulative discriminating power and probability of paternity exclusion were 0. 9878 and 0. 6648 respectively. Human sera diluted 100 times and bloodstains kept at room temperature for 4 weeks could be typed for these four blood groups correctly. The phenotypes of ORM, AHSG and GC could be determined correctly in bloodstains kept at room temperature within 24 weeks. This provides a good approach for individual identification of human bloodstains.
