The Aqueous 2 Phase System

Caption

This is a diagram of the aqueous two phase system (composed of poly(ethylene glycol) [PEG] and salt phases) used to pre-purify yersiniabactin from the crude extract of a cellular culture used to produce the compound. The compound, complexed to iron, is separated and concentrated into the PEG phase of the system and simplifies and improves subsequent steps at final purification.
