Anti-XK related 9 antibodies are used for the immunodetection of the protein encoded by the XKR9 gene. In humans, the canonical protein has a reported length of 373 amino acid residues and a mass of 43.4 kDa. Its subcellular localization is in the cell membrane. A member of the XK protein family, it is known to be involved with the apoptotic pathway. Post-translational modifications have been described, including protein cleavage. Other names for this target antigen include X Kell blood group precursor-related family, member 9, X-linked Kx blood group related 9, XK, Kell blood group complex subunit-related family, member 9, and XK-related protein 9. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Indicated applications for XK related 9 antibodies listed below include Immunocytochemistry, Immunofluorescence, and Immunohistochemistry.
