FIG. 6.
Detection of F-actin in spermatozoa. Spermatozoa were stained with rhodamine phalloidin and photographed by fluorescence microscopy. (A) Spermatozoan from a wild-type mouse. The entire spermatozoan is stained, but the level of staining is highest in the middle piece. (B) Spermatozoan from a nectin-2−/− mouse. Staining is predominantly in the head.
