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

MUC5AC (gastric mucin) belongs to the gel-forming mucin family of glycoproteins, the major components of the protective mucus layer on the mucosal surfaces of epithelial tissues. Mucus protects the tissue surface from mechanical damage, stabilizes the luminal microenvironment, and traps pathogens including bacteria and viruses for mucociliarly clearance. MUC5AC, like other family members, is differentially expressed. MUC5AC is expressed in airway and gastric epithelial cells and highly expressed in colorectal carcinomas. Although not normally detected by antibody in adult colon, MUC5AC is detectable in fetal colon. It is thought that positive MUC5AC antibody staining in colorectal cancer may be due to the resurgence of MUC5AC expression or the unmasking of an embryonic MUC5AC antibody reactive epitope during tumorigenesis. There are qualitative and quantitative alterations of MUC5AC expression in association with various pathological conditions. For example, S dysentariae infection induced MUC5AC expression in HT29 cells which was inhibited by polymyxin B pretreatment (Raja et al, 2011). Antibody studies identified elevated MUC5AC levels in benign and malignant gallbladder lesions (Xiong et al, 2011). On the other hand, MUC5AC expression is decreased or has abnormal glycosylation in the goblet cells of conjunctiva in a number of eye inflammatory conditions including Sjogren, Steven-Johnson and dry eye syndromes (Contreras-Ruiz, 2012). The MUC5AC clone 45M1 antibody is widely used. For example, it has been used as part of an antibody panel to help distinguish esophageal adenocarcinoma (MUC5AC/+) from squamous cell carcinoma (MUC5AC/-) (DiMaio et al, 2012)

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.
