Anti-PANX1 antibodies are used in the immunodetection of the protein pannexin 1. In humans, the canonical protein has a reported length of 426 amino acid residues and a mass of 48.1 kDa. Its subcellular localization is in the ER and cell membrane. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the Pannexin protein family, PANX1 is reported to be a structural component of the gap junctions and the hemichannels involved in the ATP release and nucleotide permeation. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include OOMD7, OZEMA7, PX1, UNQ2529, innexin, and MRS1. PANX1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 110 citations in the literature describe the use of PANX1 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
