To determine the association between the onset of uterine beta-glycoprotein secretion in rabbits 144 hr postcoitum and increasing proteolytic activity uterine secretions were purified by ion-exchange chromotography polyacrylamide (PAA) disc electrophoresis and cellulose acetate electrophoresis. Significant protease activity of uterine secretion from one dose 162 hr postcoitum was detected by film gelatine lysis of the purified uterine protein fractions. No activity was observed at 120 hr. Slight activity was observed at 144 hr. After isolation of the uterine proteins from secretions at 162 hr by gel and ion-exchange chromotography proteolytic activity was found only in the beta-glycoprotein fraction. Beta-glycoprotein may be involved in the dissolution of the zona pellucida to permit implantation.
