A previously unrecognized esterase from the sera of the appropriate strains of the rat Rattus norvegicus was revealed by a discontinuous polyacrylamide gel electrophoretic technique. This esterase migrated in the albumin region, whereas a previously known major albumin esterase controlled by the Es-2 locus migrated in the postalbumin region when the method was used. The new albumin esterase component which separated from the Es-2 esterase was identified as the product of the Es-1b gene. The new albumin esterase was not detectable in the sera of sexually mature males of the appropriate genotype, because the activity level of this esterase was influenced by sex hormones, especially androgen.
通过不连续聚丙烯酰胺凝胶电泳技术，在褐家鼠（Rattus norvegicus）合适品系的血清中发现了一种以前未被识别的酯酶。在使用该方法时，这种酯酶在白蛋白区域迁移，而由Es-2位点控制的一种先前已知的主要白蛋白酯酶则在后白蛋白区域迁移。从Es-2酯酶分离出来的新的白蛋白酯酶成分被鉴定为Es-1b基因的产物。在具有合适基因型的性成熟雄性血清中检测不到这种新的白蛋白酯酶，因为这种酯酶的活性水平受性激素尤其是雄激素的影响。
