Figure 7
Effect of heparin on the intensity of the tyrosine residue peak at 830 cm−1, the protein bands at 890 and 1250 cm−1, the phospholipid peak (GM1) at 1020 cm−1 and the lipid bands at 1745 and 1445 cm−1. Black lines and markers correspond to data from the equatorial segment (ES) region and red lines and markers to data from the apical acrosomal vesicle (AA).
