【摘要】 采用垂直板状聚丙烯酰胺梯度凝胶电泳 ,对企鹅珍珠贝鳃组织的酯酶 (EST)、葡萄糖 6磷酸脱氢酶 (G6PD)、乳酸脱氢酶 (LDH)、苹果酸脱氢酶 (MDH)和超氧化物歧化酶 (SOD) 5种同工酶进行了检测 ,并对酶谱特征进行了生化遗传分析。酶谱表型显示企鹅珍珠贝的同工酶呈现多态现象 ,同工酶表达上的多态性表明企鹅珍珠贝具有较丰富的遗传多样性。更多还原

【Abstract】 Isozymes of EST, G6PD, LDH,MDH and SOD from the gill tissue of marine mollusca (Pteria penguin Rding ) were analyzed by vertical polyacrylamide gradient gel electrophoresis. The isozyme diversities of Pteria penguin are very obvious. The results show that expression of enzyme at gene loci and the activity of isozyme are varied with different samples. It indicates that significant genetic diversity exists in Pteria penguin.更多还原
