Anti-Mucin 5B Antibody, clone 19.4E

Mucins are a family of highly glycosylated proteins that are present on the surface of, and are secreted by, many glandular epithelial cells. Mucins provide a barrier between the luminal membranes of cells in the epithelium and their environment. For instance, in the digestive tract, the mucin barrier protects the epithelial cells from the action of proteolytic enzymes. These high molecular weight glycoproteins consist of a nonglobular protein backbone (apomucin) and many O-linked glycans. Salivary Mucin 5B proteins are some of the largest polypeptides, with molecular weights ranging from 14 - 40 x 10³ kDa.

Un-glycosylated, serine- and threonine-free synthetic peptide from the N-terminus of human MUC5B.

Detect Mucin 5B using this Anti-Mucin 5B Antibody, clone 19.4E validated for use in ELISA, WB, IH.

Western blot; Bands in the high molecular weight range of 200kDa or above are expected for highly glycosylated proteins.

Immunohistchemistry: Paraffin sections. Deglycosylating the tissue is critical to expose epitope. There are a number of deglycosylation protocols available and a discussion of these related to Mucin can be found in Cao, Y. et al. (1997)(see references).
