## Abstract In this study the use of an aqueous twoβphase system (ATPS) following the direct chemical extraction of a recombinant viral coat protein, from the cytoplasm of __Escherichia coli__, is evaluated. The driving force is the need to establish an economicallyβviable process for the manufactu

Aqueous two-phase systems containing two polymers are a mild separation method for biomolecules due to the high concentration of water (75-90% ) in the phases. The phase systems have been further developed by introduction of thermoseparating polymers which make recycling of phase components possible
An effective system has been developed for purification of apolipoprotein A-1 from Escherichia coli fermentation solution and human plasma using aqueous two-phase extraction and thermal-phase separation. The system included non-ionic surfactants (Triton or Tween) and as top phase-forming polymer a r
