Figure 4From: Oocyte activation and phospholipase C zeta (PLCζ): diagnostic and therapeutic implications for assisted reproductive technologyImmunofluorescent localisation of PLCζ (red) in (A) hamster and (B) human sperm. Fluorescein isothiocyanate-conjugated peanut agglutinin (FITC-PNA)-lectin staining (green) identifies the acrosome, and Hoescht-33342 staining (blue) identifies the nuclei. Arrows indicate the immunolocalisation of PLCζ within the acrosome and equatorial segment of hamster and equatorial segment of human sperm. DIC: differential interference contrast.
