Fig. 9. Binding of sperm FUT5 to intact human zona pellcuida. Human oocytes were incubated with (A) 150 pmol/ml Alexa-Fluor 488 sperm FUT5, (B) 150 pmol/ml Alexa-Fluor 488 sperm FUT5 + 50-fold excess of unlabeled sperm FUT5, or (C) 150 pmol/ml Alexa-Fluor 488 ovalbumin. The results shown are representative of two replicate experiments.
