Immunostaining of rat cerebellar sections with AS382 antibody directed against the 2nd intracellular loop of the V2a receptor (A), or with the AS382 antibody pre-absorbed with the antigenic peptide TLD2 (B), or with the pre-immune serum (C), or with an antiserum (AS C-3) directed against the V2b splice variant (D), with the antiserum pre-absorbed with the V2b antigenic peptide (E) or with the pre-immune serum (F). PC, Purkinje cells; PC dendrites (arrows). Scale bars,20 μm. Images are representative of two independent experiments.
