Fig. 4.

Localization of the C2 and C2′ segments of NMDAR1 in striatal nNOS neurons. The panels on the leftillustrate staining for the C2 segment (A) and the C2′ segment (C). The panels on theright illustrate staining for nNOS. The antibody to the C2 segment produces staining of the cytoplasm of most striatal neurons and fairly intense punctate staining of the striatal neuropil. Both nNOS-positive and nNOS-negative cells are stained for the C2 segment (A, B). The antibody to the C2′ segment stains only a small number of striatal cells. The nNOS-ir neurons are stained intensely, but other C2′ stained cells do not stain for nNOS (C, D). Scale bar, 20 μm.
