SIMULTANEOUS PHENOTYPING OF ORM, PI, AHSG AND GC IN HUMAN BLOODSTAINS USING PAGE IEF IMMUNOASSAY / 中国法医学杂志

ABSTRACT

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.
