Anti-ITF antibodies enable researchers to detect and measure the ITF antigen in biological samples. This target is a reported synonym of the TFF3 gene, which encodes trefoil factor 3. This protein is known to function in carbohydrate metabolism and homeostasis, among other biological roles. The human version of ITF has a canonical amino acid length of 80 residues and a protein mass of 8.6 kilodaltons. It is reported to be localized in the extracellular matrix, cytoplasm, and is secreted of cells and notably expressed in the duodenum, colon, cervix, bronchus, and appendix. Western Blot is the most common application for the ITF antibodies listed below. ELISA, Immunocytochemistry, and Immunohistochemistry are also common applications.
