Urea has been used to dissociate and solubilize proteins for isoelectric focusing (electrofocusing) in acrylamide gels (llJ8) and sucrose gradient columns (2,3,4,17). In using concentrated urea (7 M) in electrofocusing experiments with whole bovine casein, we observed that the pH of the ampholyte gr
