Starch gel electrophoresis of erythrocyte hypoxanthine-guanine phosphoribosyl transferase and adenine phosphoribosyl transferase: a population survey.

Vertical starch gel electrophoresis of hypoxanthine-guanine phosphoribosyl transferase (HGPRT) and adenine phosphoribosyl transferase (APRT) was performed in several population groups including Caucasians, Negroes and Orientals. The red cells of a total of 244 individuals were examined for HGPRT and those of 265 for APRT and no variants were detected.
