Abstract
In addition to its application as a separation process, aqueous two-phase partitioning often yields information on important physical properties of proteins, replacing other more cumbersome analytical techniques. For example, aqueous two-phase partitioning can be used to measure the hydrophobicity and charge of a protein (1-3), to calculate dissociation constants between enzymes and substrates (4), to fractionate cell populations (5), or to characterize cell surfaces (6,7).
