Abstract: | Poly(ethylene glycol) and dextran aqueous two-phase systems (ATPS) were developed to facilitate the separation of components of the proteose peptone fraction of bovine milk, which are mostly large casein derived peptides or glycoproteins. These have proved difficult to purify using conventional chromatographic procedures. ATPS exploit differences in hydrophobicity, size and ionic properties of the proteose peptones with a view to developing methods for future large scale preparations of the individual components of this whey protein fraction. |
