摘要
用大鼠精核蛋白（Ｒａｔ Ｐｒｏｔａｍｉｎｅ，ＲＰ）－核糖核酸（ＲＮＡ）复合物（ＲＰ－ＲＮＡ Ｃｏｍｐｌｅｘｅｓ）免疫大鼠，得到了特异的抗ＲＰ抗血清，并用Ｉｍｍｕｎｏｄｏｔｔｉｎｇ和Ｉｍｍｕｎｏｂｌｏｔｔｉｎｇ方法验证了其特异性。该抗血清和ＲＰ有特异的反应，并和哺乳动物小鼠和羊的精核蛋白有一定程度交叉反应，而与体细胞类型核蛋白（Ｈ１，Ｈ２ａ，Ｈ２ｂ，Ｈ３，Ｈ４）无交叉反应。并对制备该抗血清的意义予以讨论。
Specific polyclonal antisera against rat protamine (RP) using RP-RNA complexes as an antigen have been obtained. The specificity of antibodies was determined in immunedotting and immunoblotting assays. The antisera reacted specifically with RP, but not with somatic nuclear proteins, the antisera may cross-react with mouse and ram protamines. The significance of antisera against protamine was discussed.
