Abstract
Mammalian fertilization is a multi-step process with different requirements for specificity at each step. In the present report we have examined the binding of spermatozoa to homologous and heterologous zonae pellucidae. The homologous zona binding proteins (ZBP) of ejaculated rabbit, pig and human spermatozoa and epididymal mouse spermatozoa have been identified. The rabbit's ZBPs have relative molecular weights (MW) of 32K, 18K, 16K and 14K; the pig's major ZBP is 16K while human spermatozoa bind human zona protein at 17K and 18K. Mouse sperm ZBPs are 19K, 18K and 16K.Entities:
