Fig. 6.
Immunolocalization of SERT (red) and 5-HT7 (green) in MCF10A membranes. Representative Z-plane cross-sectional images of a representative apical cell. Note that the SERT and 5-HT7 immunoreactivity were largely nonoverlapping, with SERT associated with the apical and 5-HT7 associated with the basolateral membranes.
