Acrylamide gel electrophoretic patterns of human serum alkaline phosphatase activity-- a population study in the...

Akaline phosphatase activity following polyacrylamide gel electrophoresis of human sera obtained from normal populations in the Eastern India shows a correlation between the presence of p++ phenotypes with the B and O blood groups only in females. The incidence of additional bands in the beta-lipoprotein zone is much higher in female samples than in males. The frequencies of both p++ and p+ henotypes within the different endogamous communities and castes are rather variable. Electorphoresis following heat treatment of sera obtained from pregnant females shows the complete absence of p++ and p+, as also of bands at the beta-lipoprotein zones in them.
