Anti-SML1 antibodies enable researchers to detect and measure the SML1 antigen in biological samples. This target is a reported synonym of the TFF2 gene, which encodes trefoil factor 2. This protein is reported to inhibit gastrointestinal motility and gastric acid secretion. The human version of SML1 has a canonical amino acid length of 129 residues and a protein mass of 14.3 kilodaltons. It is reported to be a secreted protein that is notably expressed in the stomach, rectum, duodenum, colon, and appendix. This target antigen may also be known as SP. A number of SML1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
