Figure 7. Possible role of carbohydrates on sperm binding. (A) Effect of metaperiodate treatment on sperm binding to live eggs. (B) Effects of Pronase-digested VE glycopeptides on sperm-egg binding. A total of 5 μg of gp69/64 (1:1) and proportional amounts of other VE proteins were used according to the ratio indicated in Fig. 3. The sperm binding level in the presence of an equal amount of heat-inactivated Pronase was used as a control and designated as 100%. Bars represent SD with n = 15 eggs.
