Fig. 1From: Immunolocalization of G protein-coupled estrogen receptor in the rat epididymisImmunolocalization of GPER in adult Wistar rats. GPER immunostaining is observed primarily in the principal cell cytoplasm (red color) within the corpus and cauda. Immunostaining is strongest near the apical membrane (arrows). No immunostaining was observed when slides were incubated with pre-absorbed primary antibody. Bar = 100 μmBack to article page
