Membrane vesicles with a high mating reactivity were obtained from cilia of Paramecium caudatum by treatment with a solution containing 2 M urea and 0.1 mM Na2-EDTA. All processes of conjugation were induced in cells of the complementary mating type by approximately 10 mug/ml proteins of the vesicles. Electron microscope observation showed that the membrane vesicles have a diameter of 100-150 nm. Electrophoretic analysis on SDS polyacrylamide gel revealed no significant difference in polypeptide patterns of the particles from the two complementary mating types.
通过用含有2 M尿素和0.1 mM Na2-EDTA的溶液处理,从尾草履虫的纤毛中获得了具有高交配反应性的膜泡。通过大约10微克/毫升的膜泡蛋白在互补交配型细胞中诱导了所有的接合过程。电子显微镜观察表明,膜泡的直径为100-150纳米。在SDS聚丙烯酰胺凝胶上的电泳分析显示,来自两种互补交配型的颗粒的多肽模式没有显著差异。
