Abstract
Hamster and bovine zonae pellucidae were dissolved by heating them in buffered saline for 35 min at 65°C and 80°C, respectively. Pretreatment of noncapacitated sperm with these solutions did not affect their binding to eggs, but the binding of cumulus-capacitated hamster sperm and of bovine sperm that had undergone a capacitation-like surface change in response to hypertonic-treatment was severely curtailed. These experiments demonstrate that such zona solutions exhibit receptor activity, but only for the capacitated sperm.
