Anti-Mucin 7 antibodies enable researchers to detect and measure the Mucin 7 antigen in biological samples. This target is a reported synonym of the MUC7 gene, which encodes mucin 7, secreted. This protein is believed to function in a protective capacity by promoting the clearance of bacteria in the oral cavity and aiding in mastication, speech, and swallowing. The human version of Mucin 7 has a canonical amino acid length of 377 residues and a protein mass of 39.2 kilodaltons. It is reported to be a secreted protein that is notably expressed in the salivary gland. Other names for this target antigen include MG2 and mucin-7.
