Description générale

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.

Application

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

Actions biochimiques/physiologiques

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.

Notes préparatoires

Prepared according to the method of Glenister, et al., for use in complex growth media for dental plaque bacteria.
