Anti-Smuc antibodies enable researchers to detect and measure the Smuc antigen in biological samples. This target is a reported synonym of the MUC2 gene, which encodes mucin 2, oligomeric mucus/gel-forming. The human version of Smuc has a canonical amino acid length of 5289 residues and a protein mass of 550.9 kilodaltons. It is reported to be a secreted protein that is notably expressed in the small intestine, rectum, duodenum, colon, and appendix.
