MUC5AC Antibody (45M1) Summary

• Immunogen: M1 mucin preparation from the fluid of an ovarian mucinous cyst belonging to an O Le(a-b) patient
• Localization: Cytoplasmic
• Specificity: This MAb recognizes the peptide core of gastric mucin M1 (>1,000 kDa) (recently identified as Mucin 5AC). Its epitope is destroyed by beta-mercaptoethanol and proteases but not by periodate treatment. Antibody to gastric mucin M1 reacts with the gastric epithelium of normal human gastrointestinal tract as well as with the precancerous and cancerous colon but not with normal adult colon. It also reacts with fetal colonic mucosa. Resurgence of gastric mucin reactivity during colonic carcinogenesis is due to re-expression of the peptide core of gastric (or fetal colonic) mucins.

Background

Mucin 5, subtype AC (MUC5AC) is a gel-forming secreted mucin that functions as a protective barrier on surface of epithelial tissues (1-2). MUC5AC is expressed primarily by goblet cells of the surface epithelium, including in the stomach, respiratory tract, gall bladder, endocervix, and endometrium (1-3). Human MUC5AC is located on chromosome 11p15.5, consisting of 5654 amino acids and has a N-terminus, tandem-repeat region (TRR), and a C-terminus, with a theoretical molecular weight of ~585 kDa (1-4). More specifically, the N-terminus contains four von Willebrand factor type D domains, where D1 also has a leucine zipper pattern (1). The TRR is further divided into nine CysD domains and four PTS-rich tandem repeats (1). Finally, the C-terminus has a D4-, B-, C-, and CK-domain (1). The TRR is a site of heavy O-glycosylation that functions in gel and polypeptide formation (1,3).

Given that MUC5AC is the primary mucin produced and secreted by cells lining airway, it is understandable that its expression is dysregulated in a number of respiratory diseases (1,3,5,6). For instance, MUC5AC is overexpressed in asthma and the protein is also more highly glycosylated, specifically fucosylated, in the disease state (1,3,7). Additionally, its overproduction is a key feature in chronic obstructive pulmonary disease (COPD) contributing to mucosal blockage (6). Multiple pathways are associated with overproduction of MUC5AC including NFkappaB, the primary pathway for production and secretion, and also the MAPK and STAT6 pathways (3). In addition to conventional, synthetic therapeutics agents, researchers are exploring natural MUC5AC inhibitors such as flavonoids, glycosides, and steroids to treat associated disorders (3).

FAQs for MUC5AC Antibody (NBP2-15196). (Showing 1 - 1 of 1 FAQs).

1. I would be interested in buying the anti-Mucin 5AC (clone 45M1). However, the antibodies from Abcam (your competitor), also clone "45M1" does not work in the rat. On your datasheet, you announce your antibody "cross React" with different species, including rats. Can you please confirm me?
   • Our Mucin 5AC antibody NBP2-15196 has rat and other species listed as possible cross reactive species based on homology. The Abcam antibody of the same clone also lists rat as a potential species. Unlike Abcam, we will apply our guarantee to species that have 90% homology or higher.
