H-Y抗血清的制备及检测研究

选用８ ～１２ 周龄纯系的 Ｂ Ａ Ｌ Ｂ／ Ｃ 母鼠， 用同日龄的 Ｂ Ａ Ｌ Ｂ／ Ｃ 公鼠采取皮肤移植和脾细胞注射２ 种方式免疫， 制备 Ｈ Ｙ 抗血清， 经精子微量细胞毒性试验， 筛选抗血清。皮肤移植５ 只小鼠中只有１ 只产生较好的抗血清， 脾细胞注射的４ 只小鼠都能产生较好的抗血清， 产生抗血清的小鼠占５５ ％ 。抗血清与昆明鼠正常８ｃｅｌｌ 早期桑椹胚培养５ ～６ 、１８ 和２４ ｈ 后， 退化率达４３３ ％ ， 经 Ｘ２ 检验差异不显著（ Ｐ ＞ ００５） ， 符合自然性比例。

Preparation and Detection of H Y Antisera

H Y antisera were produced in 8～12 weeks old BALB/C female mice by skin grafts and repeated intraperitioneal injections of syngenetic male spleen cells.Sperm microcytotoxicity test was used to detect antisera.Five of nine produced high titer antisera,one by skin grafts and four by injections of spleen cells.After cultured with H Y antisera for 5～6,18 and 24 h,43 3% embryos at 8 cell early stage were affected but showed no significant difference in sex ratio from the normal (ones)(1∶1,P>0 05).
