Anti-XK related 7 antibodies are used for the immunodetection of the protein encoded by the XKR7 gene. In humans, the canonical protein has a reported length of 579 amino acid residues and a mass of 63.8 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. Other names for this target antigen include X Kell blood group precursor-related family, member 7, X-linked Kx blood group related 7, XK, Kell blood group complex subunit-related family, member 7, and XK-related protein 7. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Immunohistochemistry is a widely used application for the XK related 7 antibodies listed below. In addition, ELISA is also a common application.
