Figure 2From: Molecular and functional characterization of voltage-gated sodium channels in human spermImmunofluorescent localization of voltage-gated Na+ channels in human sperm. Immunofluorescence and corresponding phase-contrast images of sperm cells stained with primary antibodies against Nav1.1–1.9 and Nax showing specific localizations for each Na+ channel. Experiments were performed at least six times for each channel with similar results. Scale bar: 20 μM.Back to article page
