摘要: 采用聚丙烯酰胺梯度凝胶垂直板电泳,分析了大口鲇和鲇鱼的血清蛋白质以及心脏、肝脏、眼和肌肉4种组织的EST及MDH同工酶。结果表明,大口鲇和鲇鱼的血清蛋白质均能分离出20条左右的谱带,两者既表现出相同的谱带,又表现出迁移率和含量都不同的带型。两者的EST和MDH同工酶在4种组织及血清中均能特异性地表达,存在明显的组织和物种特异性。本文认为肝脏是研究大口鲇和鲇鱼种群生化遗传结构与变异的理想材料,同时还探讨了两种鲇鱼的M DH同工酶位点。
Abstract:The serum proteins and isozymes in four tissues (heart,liver,eye and musele)of Smeridionalis Chen and S.asotus Linnaeus were analyzed by polyacrylamide gradient gel vertical electrophoresis.The isozymes are esterase(EST)and malate dehytrogenase(MDH).The results showed that electrophoretograme of serum proteins were about 20 protein pattens in two species catfish,they were either the same protein pattens or the different pattens.Electrophoretogram of isozymes(EST,MDH)in two species catfish indicated tissues and species specificity.Experiment considered that the liver was a good material studied biochemical genetic constitution and variation in species group of S.meridionalis Chen and S.asotus Linnaeus.
