title: Partition of proteins in aqueous polymer two-phase systems and the effect of molecular weight of the polymer.
abstract: The partition of substances in aqueous polymer two-phase systems is influenced by the molecular weight of the phase-forming polymers. We investigate how the effect of the molecular weight of the polymers depends on the molecular weight of the partitioned protein. We show that the magnitude of change of the partition is very small for proteins of molecular weights around 10,000, but increases almost linearly up to molecular weights of 250,000.
