Cacng2 immunofluorescence in the mouse DRG. Fluorescence micrograph from a 12-μm cryosection of a naïve CBA/J mouse L5DRG incubated with antibodies against Stargazin (Cacng2 gene product). Cytoplasmic immunolabeling of varying intensities is seen in neurons of all sizes, but most prominently in neurons of larger sizes.
