8种家兔血清LDH同工酶电泳分析

利用不连续梯度聚丙烯酰胺圆盘凝胶电泳法，对新西兰兔，青紫蓝兔，比利时兔，日本大耳兔，加利福尼亚兔，德国巨兔，长毛兔，哈白兔等８个品种家兔血清的乳酸脱氢酶同工酶进行电泳分析。结果表明，聚丙烯酰胺凝胶电泳能很好地分离出家兔血清中的５种ＬＤＨ同工酶；家兔血清ＬＤＨ同工酶谱的区带分布具有种的特异性；家兔５因清ＬＤＨ同工酶以Ｂ亚基占优势，Ａ，Ｂ亚基的比率反映家兔的亲缘关系。

Analysis on Serum lactate Dehydrogenase in Eight Species of Rabbits using Electrophoresis

Eight species rabbits were used to study the lactate dehydrogenase (LDH) by means of discontinuity polyacrylamide gel electrophoresis. The results of experiment indicates that five species LDH isozyme of rabbit could be primly separate by polyacrylamide gel electrophoresis; there were distinct characters of species in the isozyme-spectra of LDH of rabbits' serum; the B sub-radix is ascendant than A sub-radix, the rate of A and B relation reflects the kin of rabbits; We estimate the heterosis of rabbits breed combined.
