Fig. 2. Effects of an anti-
6, anti-CD151 or anti-CD9 mAb on human sperm-egg fusion. Zona pellucida-free human eggs were incubated with the blocking anti-
6 mAb GoH3 (A) the anti-CD151 mAb 11B1G4 (B) or the anti-CD9 mAbs SYB-1 and ALB-6 (C) before and during insemination with human sperm. Lines represent the mean ± s.d. from five different experiments. The number of eggs used in each condition is given above. *Significantly different from control (P<0.001).
