From: Expression of AMPA receptor subunits at synapses in laminae I–III of the rodent spinal dorsal horn
PSD-95 immunostaining in dorsal horn. a: The distribution of PSD-95-immunoreactivity in the rat dorsal horn following antigen retrieval with pepsin. Approximate positions of the laminae are shown. Punctate staining for PSD-95 is present throughout the dorsal horn, with the highest density in the superficial part (laminae I–II). b-g show immunostaining for GluR2 (green) and PSD-95 (red) in lamina II in a wild-type mouse (b-d) and in a PSD-95 mutant mouse (e-g). Note the lack of punctate staining for PSD-95 in the PSD-95 mutant. All images are from single optical sections. Scale bars = 50 μm (a), 10 μm (b-g).
