Staining of rabbit retina with antibody R-1563-100. NMDAR 2B immunoreactivity (red) was confined in the entire plexus of the IPL. Ocassionally there were labelled blood vessels. Cryostat sections of rabbit eyecaps were incubated overnight in NMDAR 2B antibody (1:1,000) at RT. Donkey anti-rabbit Cy3 secondary (1:1,000) was used. (INL = inner nuclear layer, IPL = inner plexiform layer, GCL = ganglion cell layer). Photo courtesy of Alejandro Vila, Univ of Texas Health Science Center, Houston, Texas.
