Anti-TM9SF2 antibodies are used in the immunodetection of the protein transmembrane 9 superfamily member 2. In humans, the canonical protein has a reported length of 663 amino acid residues and a mass of 75.8 kDa. Its subcellular localization is in the endosome, Golgi, and cytoplasm. It is ubiquitously expressed across many tissue types. A member of the Nonaspanin (TM9SF) (TC 9.A.2) protein family, TM9SF2 is known to be involved with metabolic processes. Synonyms for this target antigen include P76, 76 kDa membrane protein, LncRNA Positively Correlated with Inflammatory Responses, dinucleotide oxidase disulfide thiol exchanger 3 superfamily member 2, and Lnc-PCIR. TM9SF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some Tm9sf2 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
