泥鳅和大鳞副泥鳅酯酶同工酶的比较研究

采用不连续聚丙烯酰胺凝胶电泳技术分析了泥鳅和大鳞副泥鳅的性腺、脑、肾、肝和心脏五种组织的酯酶同工酶。结果表明 :在不同器官中酯酶同工酶存在明显的组织特异性 ;比较泥鳅和大鳞副泥鳅酯酶同工酶它们的酶谱相似外 ,在它们的各个相应组织之间也显示出差异 ,表明酯酶同工酶在泥鳅种内具有一定的差异。这对于探讨泥鳅不同种之间的亲缘关系将是一个很有用的手段。本文认为肝脏是研究泥鳅与大鳞副泥鳅种群生化遗传结果的理想材料

Comparative studies on the esterase isozyme patterns of Misgurnus auguillicaudatus and Paramisgurnus dabryanus

The polyacrylamide gel eletrophoresis was used to analyse the esterase isozyme patterns of five tissues including goand, brain, kidney, liver and heart in M. auguillicaudatus and P.dabryanus . The results showed that:esterase isozymes are specific in these two loaches and are different between the same tissues of different species. Considering the diversity of esterase isozymes, the liver is ideal material for the studies of population genetic and biochemical structure of M. auguillicaudatus and P.dabryanus .
