P2X purinoceptor 5 is a protein that in humans is encoded by the P2RX5 gene. The product of this gene belongs to the family of purinoceptors for ATP. This receptor functions as a ligand-gated ion channel. Several characteristic motifs of ATP-gated channels are present in its primary structure, but, unlike other members of the purinoceptors family, this receptor has only a single transmembrane domain. Four transcript variants encoding distinct isoforms have been identified for this gene.

Western blot analysis of P2RX5 on 10% mouse heart lysate with Rabbit anti-P2RX5 antibody (ER2001-36) at 1/1,000 dilution
Exposure time: 60 seconds; ECL: K1801
Blocking: 5% NFDM/TBST, 1 hour at room temperature Primary antibody: ER2001-36, 1/1,000 in 5% BSA, 2 hours at room temperature Secondary antibody: Goat anti-Rabbit IgG-HRP (HA1001), 1:5,000 in 5% NFDM/TBST, 1 hour at room temperature

Immunohistochemical analysis of paraffin-embedded mouse brain tissue using anti-P2RX5 antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0-8.4) for 20 minutes.The tissues were blocked in 5% BSA for 30 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (ER2001-36, 1/200) for 30 minutes at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
