Membrane protein isolation by in situ solubilization, partitioning and affinity adsorption in aqueous two-phase systems - Purification of the human type 1 11 beta-hydroxysteroid dehydrogenase
Recently developed aqueous two-phase systems based on non-ionic detergents and polymers are suitable for the separation of membrane proteins. Moreover, within this relatively membrane protein "friendly" environment, changes in temperature can be controlled and stabilizing agents may be added to ensure integrity of the target protein during isolation. Here, we use aqueous two-phase partitioning for
