Characterization and application of a new aqueous two phase system based on gum acacia (ex.Acacia senegal), a naturally occuring polysaccharide,and polyethylene glycol

Summary Gum acacia has been used with polyethylene glycol to form a two phase aqueous polymeric system. The system followed Newtonian fluid behaviour and the acacia rich phase supported a high concentration of protein (>1.3 mg/ml) in solution. The data on partitioning of various proteins in this system indicates that it can be used for selective separation of a particular protein from a protein mixture.
