Genetic polymorphism of esterase B3 in human leukocytes.


Human tissues contain an esterase activity called ESB3, detectable by starch gel electrophoresis followed by staining with alpha-naphthyl butyrate. Using mononuclear leukocytes, we demonstrated an electrophoretic variant of ESB3. Family studies suggest that the variant is inherited as a simple Mendelian trait; individuals with the ESB3 2-1 phenotype are… (More)
