| 摘 要： | 用ＢｌｕｅＳｅｐｈａｒｏｓｅ·ＣＬ．６Ｂ亲和层析方法分离纯化的甲鱼ＬＤＨ＿５、甲鱼ＬＤＨ＿１和北京鸭ＬＤＨ＿５，进行比较研究。从分子量、等电点、氨基酸组成、平均摩尔差异百分比及在ＢｌｕｅＳｅｐｈａｒｏｓｅ·ＣＬ·６Ｂ层析柱上洗脱特性几方面进行比较，结果表明，两个不同纲的动物（甲鱼和北京鸭）的ＬＤＨ＿５的Ａ亚基之间的差异大于同一种动物的ＬＤＨ＿５的Ａ亚基和Ｂ亚基之间的差异，并说明不同纲的动物ＬＤＨ＿５之间具有同源性。

| Abstract: | The result of comparing behavior of affinity chromatography,physical char-acteristics and amino acid composition and average mole persent difference of animals of 2 classes of vertibrates showed that the A subunit of soft-shelled turtle and Peking duck are mor homologous to each other than are the A and B subunit of soft-shelled turtle. |
