Anti-CD164 antibodies are used in the immunodetection of the protein CD164 molecule. In humans, the canonical protein has a reported length of 197 amino acid residues and a mass of 20.9 kDa. Its subcellular localization is in the lysosomes, cell membrane, and is secreted. Up to 5 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the CD164 protein family, CD164 is a reported sialomucin that may play a key role in hematopoiesis by facilitating the adhesion of CD34(+) cells to the stroma and by negatively regulating CD34(+)CD38(lo/-) cell proliferation. CD164 is also used as a cellular marker for characterizing basophils. Synonyms for this target antigen include MGC-24, MGC-24v, MUC-24, endolyn, sialomucin core protein 24, and DFNA66. CD164 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 60 citations in the literature describe the use of CD164 antibodies in research. Flow Cytometry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
