Anti-MS4A18 antibodies are used in the immunodetection of the protein membrane spanning 4-domains A18. In humans, the canonical protein has a reported length of 400 amino acid residues and a mass of 42.2 kDa. Its subcellular localization is in the membrane. It is notably expressed in the duodenum and small intestine. A member of the MS4A protein family, MS4A18 is known to be involved with receptor-mediated signaling pathways. Synonyms for this target antigen include membrane-spanning 4-domains subfamily A member 18. MS4A18 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Indicated applications for MS4A18 antibodies listed below include Immunohistochemistry.
