孵化酶 hatching enzyme，指各种动物胚胎孵化时，从胚胎细胞所分泌的能够引起卵膜溶解的酶的总称。海胆的孵化酶是由囊胚期细胞所分泌，两栖类是由胚胎头部的额腺分泌的，而鱼类则由胚体的外胚层性或内胚层性的孵化腺细胞所分泌，无论由哪里分泌的孵化酶均为蛋白分解酶。
孵化酶(hatching enzyme,HE)是胚胎发育到特定阶段出现的一类蛋白酶,其合成表达、运输分泌以及分泌的起始与终止在时空上受到严格的调控...

Secretory granules were spherical and 0.5—1.0μm in diameter. The hatching enzyme was dissolved in the perivitelline fluid, where it gained access to the egg envelope and digested the inner layer of the egg envelope.
孵化酶进入卵周液,对卵膜内层进行消化和降解,使胚胎破膜而出。

结果表明。保温时间与酶活力相关，但与相应保温时间的卤虫卵孵化率则不相关。
The result indicated that the time of incubation was correlated with the SOD total activity, while the incubation rate was not.
一会儿之后孵化，洗去移除所有绑定的基体的解酶，补充说，这是通过把作用于酶发生颜色。
After a second incubation and washing to remove all the unbound enzyme, a substrate solution is added, which is acted upon by the bound enzyme to produce color.
结论丙烯基硫脲可抑制酚氧化酶活性而对钉螺、螺卵的成活及其产卵量、卵壳的形成、孵化率均有影响。
It is concluded that acryl thiourea effects not only snail eggs, but also their rates of egg-laying, its egg shell and the rate of breeding.
