Differences of serum esterase zymograms among three strains of rats were observed by starch-gel electrophoresis and histochemical methods.The results were summarized as follows:1) Fourteen esterase zones in rats were separated by starch-gel electrophoresis, and in these esterase zones, Es-3, Es-4, Es-5 and Es-9 zone were observed in all sera of three strains but not Es-2 and Es-6 zone.2) Sera from the USC strain didn't show Es-1 zone, the fastest migrating zone whereas sera from the Wister and the Donryu strain revealed that.3) In the slowest migrating region, serum cholinesterase isozymes (Es-13, Es-14 and Es-15 zone) showed variation among strains or individuals, and in this region the three phenotypes, ChE-I, ChE-II, and ChE-IV, were observed in both sexes.4) Es-13 zone in the ChE-I type showed considerably different activities among strains and sexes. The lowest activity was found in the USC strain and the highest in the Wistar strain, and in females the activity-levels of Es-13 zone were always higher than those in males.
