Abstract
The present invention relates to a composition for use in purification of apolipoprotein A (ApoA) or apolipoprotein E (ApoE), said composition comprising a first and a second polymeric material, wherein the first and second polymeric material are immiscible in the primary aqueous solution, and wherein the second polymeric material is amphiphilic and water soluble. The invention further relates to a process for purifying ApoA or ApoE, or variants or mixtures thereof, by first mixing ApoA or ApoE, the composition containing a first and second polymeric material and water. The resulting primary aqueous solution is maintained for a period of time sufficient for essentially separating the phases formed, and removing the phase containing the second polymeric material and the main portion of ApoA or ApoE. Subsequently, the second polymeric material is separated from ApoA or ApoE. The thus produced ApoA or ApoE can be used for the manufacture of a medicament in the treatment of atherosclerosis and cardiovascular diseases, sepsis or peripheral atherosclerosis as well as in a method for treatment of atherosclerosis and cardiovascular diseases, sepsis or peripheral atherosclerosis when admini…
