EFFECT OF PAPAIN-DIGESTED, UNIVALENT ANTIBODY AGAINST SPERM-BINDING FACTOR ON THE FERTILIZABILITY OF SEA URCHIN EGGS.

Yoshida M , Aketa K .


???displayArticle.abstract???
Papain-digested, anti-sperm-binding factor serum which has only a species-specific antibody, deprives the egg of fertilizability as well as does undigested serum. This effect is shown to be exerted by direct masking of species-specific sperm-binding sites on the vitelline layer by univalent antibodies.
