| 摘 要： | 用亲和层析，SDS-PAGE及印迹技术，从玉米精细胞中分离纯化质膜蛋白。用ConA-HRP检测获得分子量为37和39kD两种糖蛋白特异成分。用它们分别免疫小鼠得到多克隆抗体，以兔抗鼠IgG胶体金(15nm)为探针，检查此两种蛋白在精细胞质膜上的分布。免疫定位表明，37kD, 39kD多肽是玉米精细胞质膜所特异的。有关此多肽的功能有待进一步研究。

| Abstract: | Plasma membrane proteins of sperm cells from Zea mays were passed through affinity column, separated by SDS\|PAGE and stained using Con A\|HRP. The components of 37kD and 39kD glycoproteins from gel were immunized respectively mice and polyclonal antiserums were obtained. Glycoproteins of sperm cell surface can be examined using IgG(rabbit anti mouse)\|colloidal gold(15nm) as probe. The results showed that distribution of 37 and 39kD peptides on the plasma membrane surface of sperm cells of maize with visible immunogold particles to be localized. We consider that 37 and 39kD polypeptide were specific plasma membrane glycopeptides of sperm cells. Research of their function is to be continued. |
