Anti-C1QTNF9B antibodies are used in the immunodetection of the protein C1q and TNF related 9B. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 34.7 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed at low levels. C1QTNF9B is a suspected adipokine. Synonyms for this target antigen include C1q and tumor necrosis factor related protein 9B, C1q/TNF-related protein 9B, collagen triple helix repeat-containing, and complement C1q and tumor necrosis factor-related protein 9B. Some C1QTNF9B antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. In addition, Western Blot is also a common application.
