Abstract: | Acrosin was detected by immunofluorescence in the spermatozoan acrosomes of artiodactyla (bull, ram and boar), perissodactyla (horse), carnivora (dog and cat), lagomorpha (rabbit) and primates (human) using anti-bovine acrosin immunoglobulins. The results indicate that the acrosin molecules of several mammalian species possess antigenic similarities. |
