A new esterase polymorphism was identified in epididymal homogenates from inbred rat strains by polyacrylamide gel electrophoresis. The inbred rat strains showed either fast (A) or slow (B) bands. Strain distributions of the phenotypes differed from those of other esterase loci. Genetic analyses revealed that the polymorphism is controlled by codominant alleles (Es-19a and Es-19b) and is not linked to linkage groups, I, II, IV, V, VI, XIII of the rat.
通过聚丙烯酰胺凝胶电泳在近交系大鼠品系的附睾匀浆中鉴定出一种新的酯酶多态性。近交系大鼠品系显示出快（A）或慢（B）条带。这些表型的品系分布与其他酯酶基因座的不同。遗传分析表明，该多态性由共显性等位基因（Es-19a和Es-19b）控制，且与大鼠的连锁群I、II、IV、V、VI、XIII不连锁。
