General description

Mucin has a netlike, branched structure and is a secreted protein. It belongs to the category of gel-forming mucins. The gene encoding this protein is upregulated by interleukin-1β (IL-1β) and is localized on chromosome 11p15.5.


The antibody recognizes the mucin epitope g located in the peptide core of gastric mucin (>1,000 kDa). This epitope is completely destroyed by thiol reduction (using mercaptoethanol) and partially lost following trypsin proteolysis, but is stable upon periodate oxidation. The antibody stains the surface gastric epithelium of normal human gastrointestinal tract and reacts with fetal, pre-cancerous and cancerous colonic mucosa, but not with normal colon.
