Abstract
As part of a program of investigation [1, 2, 3] of problems of fertilization and early development, the senior author has prepared antisera against various materials obtained from eggs, sperm, embryos, and adults of several species of sea urchins. In the course of the tests on developing eggs, it was observed that certain of the antisera blocked cleavage very effectively. The various antisera produced against fertilizin were found to be particularly effective cleavage-blocking agents. This seemed of special interest, since fertilizin is known [1-5] to be the sperm-receptor substance that constitutes the surface coat of the egg and is now chemically rather well defined. The cleavage-blocking action was therefore further investigated. In the present paper the results of a survey of the action of various kinds of antisera are presented.
