Analysis of 6-phosphogluconate dehydrogenase isozymes by polyacrylamide gel isoelectric focusing
Three common phenotypes of 6-phosphogluconate dehydrogenase (6-PGD) were identified by enzyme visualization following isoelectric focusing in photochemically polymerized polyacrylamide gels whereas in chemically polymerized gels no activity could be detected. Gene frequencies calculated from 429 individuals were 0.9 15 and 0.085 for 6-PGD*A and 6-PGD*C, respectively, similar to the gene frequencies of Japanese samples previously reported.

A rapid and simple method for isoelectric focusing of proteins separated by SDS-polyacrylamide gel electrophoresis was described. The focusing system was composed of a polyacrylamide gel layer (7 cm in height) and a solution layer (1.2 cm in height) superimposed on the gel layer. Both layers contain
