Abstract
An aqueous two-phase protein partitioning system is disclosed which employs polyvinylpyrrolidone as the upper phase and maltodextrin as the lower phase and provides a low-cost system for protein partitioning. The system can also be employed with the amion derivatives of chlorotriazine dyes, which bind in a noncovalent manner with the PVP and serve as a ligand for the proteins to be separated.
