Abstract: | Mating-active membrane vesicles isolated from cilia of Paramecium caudatum by the urea-EDTA method were dissolved in 9 mM lithium diiodosalicylate (LIS). Membrane vesicles were reconstituted from the LIS-soluble fraction by dialysis. They showed an ability to induce conjugating pairs without prior occurrence of mating agglutination. The same kind of membrane vesicles was obtained when cilia were treated with 4 mM LIS and stored after removing LIS for two weeks. |
