General description
Application
Mucin from porcine stomach was used in studies on the binding site of the galactose-specific agglutinin PA-IL from Pseudomonas aeruginosa.[3]
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.[4]
Preparation Note
Prepared according to the method of Glenister, et al., for use in complex growth media for dental plaque bacteria.

How can I solubilize Product M1778, Mucin from porcine stomach?
1 answer-
Mucin is not readily soluble in aqueous solutions. Turbid "solutions" will form at about 5 mg/mL in 0.1 M acetate buffer, pH 5.0. To try to increase the solubility, one might try further dilution and sonication, but we have not tried this in our labs.
