Genetic Polymorphism of Plasminogen: A New Basic Variant (PLG B) and Population Study in Japanese

Abstract
Genetic polymorphism of human plasminogen in the Japanese population was studied using agarose gel isoelectric focusing followed by immunofixation. A new basic variant, PLG B, was found as a heterozygous state PLG 1-B, which was genetically determined. The allele frequencies calculated from 258 individuals were PLG1 = 0.958, PLG2 = 0.020 and PLGB = 0.022.
