Two new esterase polymorphisms (Es-7 and Es-8) were identified in the testis homogenate of laboratory rats, Rattus norvegicus, by using discontinuous gradient polyacrylamide gel electrophoresis. Es-7 expressed two phenotypes: ES-7A (fast) and ES-7B (slow). Es-8, which migrated in the cathodal region rather than the ES-7 region, also expressed two phenotypes: ES-8A (fast) and ES-8B (slow). Linkage tests among Es-2, Es-7, and Es-8 were made from backcross progeny of the mating (LEJ/Hkm x T/Hok)F1 x LEJ/Hkm. One recombinant in 51 progeny tested was observed between Es-2 and Es-7; however, recombination between Es-2 and Es-8 was not observed in the same progeny. In addition, we show that the esterase polymorphisms of Es-5 in liver homogenate and Es-3 in small intestine homogenate are identical.
通过使用不连续梯度聚丙烯酰胺凝胶电泳，在实验大鼠褐家鼠的睾丸匀浆中鉴定出两种新的酯酶多态性（Es-7和Es-8）。Es-7表现出两种表型：ES-7A（快）和ES-7B（慢）。Es-8在阴极区域而非Es-7区域迁移，也表现出两种表型：ES-8A（快）和ES-8B（慢）。从交配组合（LEJ/Hkm×T/Hok）F1×LEJ/Hkm的回交后代中进行Es-2、Es-7和Es-8之间的连锁测试。在51个测试后代中，观察到Es-2和Es-7之间有一个重组体；然而，在同一后代中未观察到Es-2和Es-8之间的重组。此外，我们表明肝匀浆中的Es-5和小肠匀浆中的Es-3的酯酶多态性是相同的。
