Immunogen

Peptide KKGWMDPQSKGIQTGRC, corresponding to amino acid residues 136-152 of mouse P2X7 receptor (Accession Q9Z1M0). Extracellular loop.

Accession (Uniprot) Number Q9Z1M0

Gene ID 18439

Peptide confirmation Confirmed by amino acid analysis and mass spectrometry.

Homology Human, rat - identical; bovine - 14/17 amino acid residues identical.

RRID AB_2341046.

Purity Affinity purified on immobilized antigen.

Form Lyophilized powder. Reconstituted antibody contains phosphate buffered saline (PBS), pH 7.4, 1% BSA, 0.05% NaN₃.

Isotype Rabbit IgG.

Label ATTO-633. Maximum absorption 629 nm; maximum fluorescence 657 nm. The fluorescence is excited most efficiently in the 610 - 645 nm range. This label is analogous to the dyes Alexa 647, Alexa 633 and Cy5 and can be used for direct flow cytometry (FACS) using the He:Ne laser.

Storage before reconstitution The antibody ships as a lyophilized powder at room temperature. Upon arrival, it should be stored at -20°C.

Reconstitution 50 µl double distilled water (DDW).

Antibody concentration after reconstitution 1 mg/ml.

Storage after reconstitution The reconstituted solution can be stored at 4°C, protected from the light, for up to 1 week. For longer periods, small aliquots should be stored at -20°C. Avoid multiple freezing and thawing. Centrifuge all antibody preparations before use (10000 × g 5 min).

Standard quality control of each lot Western blot analysis (unlabeled antibody, #APR-008), and direct flow cytometry (labeled antibody).

Applications: fc, ic, if, lci

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
