    Scientific background

    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 proinflamatory 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

    Last update: 08/01/2023

    Anti-P2X7 Receptor (extracellular) Antibody (#APR-008) is a highly specific antibody directed against an 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)-FITC Antibody (#APR-008-F) is directly conjugated to fluorescein isothiocyanate (FITC). This labeled antibody can be used in immunofluorescent applications such as direct live cell flow cytometry and immunocytochemistry.
