Anti-SAMD9 antibodies are used in the immunodetection of the protein sterile alpha motif domain containing 9. In humans, the canonical protein has a reported length of 1589 amino acid residues and a mass of 184.3 kDa. Its subcellular localization is in the cytoplasm. It is widely expressed across many tissue types. SAMD9 is known to be involved with innate immune responses. The SAMD9 gene has been associated with the disease, Tumoral calcinosis. Synonyms for this target antigen include DRIF1, M7MLS2, MIRAGE, NFTC, OEF1, OEF2, sterile alpha motif domain-containing protein 9, and C7orf5. SAMD9 gene orthologs have been reported in the rat and chimpanzee species. A number of SAMD9 antibodies have been mentioned in research publications and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, and Immunofluorescence are also common applications.
