Fluorescence pattern of pig spermatozoa stained with FITC-PNA PI for the assessment of acrosome status and sperm viability

Dead cells showing nuclear red PI fluorescence: C-D. Live cells without PI staining: A acrosome-reacted cells with uniform green FITC-PNA fluorescence of acrosome cap; B: acrosome-unreacted cells with no staining of acrosomal cap (original magnification ×1000).<p><b>Copyright information:</b></p><p>Taken from "Prostasome-like vesicles stimulate acrosome reaction of pig spermatozoa"</p><p>http://www.rbej.com/content/6/1/5</p><p>Reproductive biology and endocrinology : RB&E 2008;6():5-5.</p><p>Published online 30 Jan 2008</p><p>PMCID:PMC2266753.</p><p>
