To study the allele frequencies and their polymorphism characteristics of human platelet antigen (HPA) and human leucocyte antigen-I (HLA-I) in Chinese xi'an population, the types of HPA and HLA-I in 375 Chinese xi'an voluntary platelet donors were detected by PCR-SSP and PCR-SSO as well as flow cytometry with magnetic beads, and were analyzed. The results showed that there was no polymorphism in HPA-7-HPA-14, HPA-16 and HPA-17 which only expressed-aa type, the -bb type was only detected in HPA-3 and HPA-15, 9 out of 16 samples for the HPA-5ab phenotype simultaneously expressed HPA-15ab, the other 7 samples expressed HPA-15bb, no HPA-15aa phenotype was observed. Phenotypes detected in this study were HPA-1aa-17aa, HPA-1ab, -2ab, -3ab, -3bb, -4ab, -5ab, -6ab, -15ab and -15bb. Read More
