title: Failure of immunoperoxidase staining to detect acrosin in the equatorial segment of spermatozoa (1).
abstract: An immunoperoxidase staining procedure that readily demonstrated acrosin in the rostral portion of the acrosome failed to detect acrosin in the equatorial segment of spermatozoa representing the mammalian orders artiodactyla (bull and boar), lagomorpha (rabbit) and primate (human).
