General description

Mucins or mucus glycoproteins are the main macromolecular components of mammalian mucus.[19] It was also used in a study to evaluate the sputum smears concentrated by cyto-centrifugation for detection of acid-fast bacilli.[22]

Application

Mucin from porcine stomach was used in studies on the binding site of the galactose-specific agglutinin PA-IL from Pseudomonas aeruginosa.[21]

Packaging

Biochem/physiol Actions

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.[20]
