Comparative Analysis on the Protein Composition of Egg Chorions between Gynogenetic Silver Crucian Carp and Gonochoristic Color Crucian Carp and the Changes during Fertilization
雌核发育银鲫与两性生殖彩鲫卵壳蛋白组分的比较分析及其受精前后的变化 Comparative Analysis on the Protein Composition of Egg Chorions between Gynogenetic Silver Crucian Carp and Gonochoristic Color Crucian Carp and the Changes during Fertilization

s:Egg chorions were isolated from unfertilized and fertilized eggs of gynogenetic silver crucian carp and gonochoristic color crucian carp by homogenization and further purification techniques.Then,soluble proteins were extracted from the isolated egg chorions,and were analyzed by gradient SDS PAGE.Three differential protein bands were revealed between the gynogenetic silver crucian carp and gonochoristic color crucian carp.Furthermore,these differential proteins were demonstrated to undergo obvious changes during fertilization.It was suggested that these differential proteins should be related to the special fertilization process in gynogenetic silver crucian carp.
