nNOS distribution in wild-type and α-syntrophin null mouse quadriceps muscle. A, Immunofluorescent labeling of nNOS shows sarcolemmal staining in wild-type that is lost in the α-syntrophin null muscle. B, Immunofluorescence of serial sections of α-syntrophin null muscle shows nNOS is lost from β1-syntrophin containing fibers. Bar, 50 μm.
