The P2X7 receptor is a member of the ionotropic P2X receptor family that is activated by ATP. To date, this family is composed of seven cloned receptor subtypes, named P2X1-P2X7.
The different P2X receptors show distinct expression patterns. P2X1-6 have been found in the central and peripheral nervous system, while the P2X7 receptor is found in cells of the immune system, particularly antigen presenting cells, and microglia. The P2X7 receptor mediates the release of proinflammatory cytokines, stimulation of transcription factors and may also have an important role in apoptosis.1-3
Different techniques have been used to characterize the P2X7 receptor. Most of them investigated pores, ion channels (electrophysiology) and membrane alterations (calcium microfluorometry, dye uptake, membrane depolarization and ion influx analysis). With the introduction of flow cytometry, it is now possible to analyze multiple cell parameters such as cell cycle, cell membrane alteration, calcium influx and cell phenotype.4

Species reactivity key:
Anti-P2X7 Receptor (extracellular) Antibody (#APR-008) is a highly specific antibody directed against an extracellular epitope of the mouse protein. The antibody can be used in western blot, indirect flow cytometry, immunohistochemistry, live cell imaging, and immunocytochemistry applications. It has been designed to recognize P2X7 purinergic receptor from mouse, rat, and human samples.
Anti-P2X7 Receptor (extracellular)-mFluor™ Violet 450 Antibody (#APR-008-V) is directly conjugated to mFluor™ Violet 450 fluorophore. This conjugated antibody has been developed to be used in immunofluorescent applications such as direct flow cytometry and live cell imaging.
mFluor™ Violet 450 dye has a maximum absorption of 405 nm and maximum emission of 445 nm. These spectral characteristics make it an excellent replacement for Pacific Blue™ or Brilliant Violet™ 421 dyes. For flow cytometry applications, the labeled antibody can be detected using the 405 nm laser lane and a filter set of 450/50.
