以性腺发育第Ⅳ期的雌、雄鲤(Cyprinus carpio L.)为试材,用7％胶浓度的聚丙烯酰胺凝胶电泳分离了血清蛋白和血红蛋白。结果表明,在性成熟期的雌雄鲤鱼血清蛋白组成有差异,其血清蛋白带谱,雌鱼有14条蛋白带,雄鱼有13条带。雌、雄性血清脂蛋白和血 Serum protein and hemoglobin were separated by polyacrylamide gel electrophoresis with a gel concentration of 7% using female IV and male carp (Cyprinus carpio L.) with gonadal development as test material. The results showed that there was a difference in serum protein composition between male and female carp at sexual maturity. Serum protein banding had 14 protein bands in females and 13 bands in males. Female, male serum lipoprotein and blood
