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).

1. What is the difference between the Quantikine and Duoset ELISA kits?
   • Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
