八个品种家兔血清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方法，对新西兰兔，青紫蓝兔，比利时兔等八个品种家兔血清的ＬＤＨ同工酶进行电泳分析。实验结果表明，聚丙烯酰胺凝胶电泳能很好地分离出家兔血清中的五种ＬＤＨ同工酶；家兔血清ＬＤＨ同工酶图谱的区带分布具有种的特异性，家名义血清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，通过实验，对家兔品种组合杂种优势进行了估测。

Gel Electrophoresis Analysis of Lactate Dehydrogenase Isozymes(LDH)in the Serum of Rabbit

The LDH isozymes in the Serum of 8 breeds rabbit were analysed by discontinous polyacrylamide gel disk electrophoresis, the results showed that from the serum of rabbit 5 standard bands of LDH isozymes could be isodated clearly by discontinous polyacrylamide gel electrophoresis; the serum of different breeds rabbit had their specific bands of LDH isozymes; the B subunit was mainly in the LDH isozymes of the serum of rabbit, the rate of A subunit diuoded B subunit relative the blood relation ship of rabbits. The LDH isozymes in the serum of rabbits were analysised, we estimate the hybrid vigor of the rabbits combination.
