Scientific background
The P2X7 purinergic receptor is a member of the ionotropic P2X receptor family that is activated by ATP. To date, this family consists of seven receptor subtypes, named P2X1-P2X7, all of which have been cloned.
The various P2X receptors show distinct expression patterns. P2X1-6 receptors have been found in the central and peripheral nervous system, while the P2X7 receptor is found in cells of the immune system, particularly in antigen-presenting cells and microglia.
The P2X7 receptor mediates the release of proinflamatory cytokines and stimulation of transcription factors and may also play an important role in apoptosis.1-3
Lyophilized Powder
Anti-P2X7 Receptor Antibody (#APR-004) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunoprecipitation, immunocytochemistry, and immunohistochemistry applications. It has been designed to recognize P2X7 purinergic receptor from rat, mouse, and human samples.

Expression and upregulation of microglial P2X7 receptor in cancer.A. Immunohistochemical staining of of rat spinal dorsal horn using Anti-P2X7 Antibody (#APR-004) or Anti-P2X7 (extracellular) Antibody (#APR-008) shows that P2X7 co-localizes with CD11b, a microglia marker (two panels) and not with NeuN, a neuronal marker (lower right panel). Specificity of the antibody was tested on P2X7 knock-out mice (western blot, in upper panel). B. Western blot analysis of rat dorsal horn lysates shows that P2X7 expression increases on post-tumor day 14 (PTD 14).
