Map of P2Y ₁ receptor protein in juvenile rat cerebellar cortex. Sagital sections of P21 rat cerebellar cortex were processed for double immunofluorescence analysis. Confocal images show that P2Y₁ receptor protein (red immunofluorescence) is present on Purkinje cell (pc) bodies and ramifications, on neuropil of molecular layer (ml), on axons of the white matter irradiating into the granule layer (gl), but not on NeuN-positive granule neurons (blue immunofluorescence). The inset represents immunofluorescence analysis performed in the presence of the immunogenic peptide for P2Y₁ receptor. Scale bars = 50 μm.
