Description_x000D_ General description_x000D_ Mucin is majorly composed of carbohydrate units, crucial for structural architecture and conformation. The monomer of mucin is 640 kDa, with protein contributing to only 20% of the molecular weight. The carbohydrate component is attached to the threonine and serine side chains. Mucins are classified into secreted and transmembrane mucins._x000D_ Mucins or mucus glycoproteins are the main macromolecular components of mammalian mucus. It was also used in a study to evaluate the sputum smears concentrated by cyto-centrifugation for detection of acid-fast bacilli._x000D_ Application_x000D_ Mucin from porcine stomach has been used:_x000D_ • in the standard curve generation for quantifying mucin-2 generated during mucosal inflammation in mice_x000D_ • as a component of digestion fluid solutions in in vitro human digestion model_x000D_ • as a component of simulated saliva fluid_x000D_ Mucin from porcine stomach was used in studies on the binding site of the galactose-specific agglutinin PA-IL from Pseudomonas aeruginosa._x000D_ Packaging_x000D_ 100, 500 g in poly bottle_x000D_ Biochem/physiol Actions_x000D_ Mucin has wide pharmacological applications in drug delivery. Mucins play a protective role in inflammation. Deregulation in mucin synthesis contributes to tumorigenesis and chronic inflammation._x000D_ Mucus forms the protective cover for all epithelial surfaces. The major structural component of mucus is gel-forming mucins. The mucus layer covering the intestinal epithelium has the MUC2 mucin as its central molecule. MUC2 is produced by goblet cells.
