Abstract excerpt

OBJECTIVE: To investigate the molecular mechanism of B antigen weaken expression in 4 cases of ABO blood group samples. METHODS: ABO blood group phenotypes were detected by micro-column gel method and saline test tube method. Exon 1-7 and promoter region of the ABO gene were amplified by polymerase chain reaction (PCR) and PCR products were directly sequenced. RESULTS: Mixed agglutination occurs between RBC and B...
