Figure 1From: Molecular and functional characterization of voltage-gated sodium channels in human spermVoltage-gated Na+ channel gene expression in human sperm. Agarose gel showing expression of messenger RNA for voltage-gated Na+ channel α and β subunits and Nax in human testis and sperm. The specific bands were not detected in the negative controls and the one with no added RNA in the reverse transcriptase reaction is shown. M, molecular weight standards.Back to article page
