The concentrations, molecular weights and isoelectric points of proteins present in muscadine grape cultivars were determined. The total protein contents of these grapes, are consistent with values reported in literature for V. vinifera grape proteins. Molecular weights of most of the protein fractions were, however, relatively high when compared with those of other grape cultivars. Isoelectric’ points of muscadine proteins ranged between pH 5.6 and pH 7.6.
