To obtain information on the remodeling of sperm chromatin during male pronuclei formation, we have followed the sperm specific histones (SpH) that form the nucleosomal core by Western imunoblot analysis with policlonal antibodies directed against the core SpH. The results obtained indicate that the
The antigenic composition of the sperm surface in Para. centrotus lividus Lain. and Sphaereehinus granularis Lain. was studied using the sperm agglutination test with homologous and heterologous antisera. The results indicated that sperm of both species have at least one antigenic determinant locate
