ABSTRACT:
The present invention relates to a process for purifying apolipoprotein A (ApoA) or apolipoprotein E (ApoE) from human plasma, by obtaining a fraction of human plasma containing said ApoA or ApoE, prepurifying said fraction in at least one step, binding said ApoA or ApoE to an anion-exchange chromatography gel, and thereafter eluting said ApoA or ApoE from said anion-exchange chromatography gel. The thus produced ApoA or ApoE can be used for the manufacture of a medicament in the treatment of atherosclerosis and cardiovascular diseases, or peripheral atherosclerosis and sepsis as well as in a method for treatment of atherosderosis and cardiovascular diseases, or peripheral atherosclerosis and sepsis when administered in a therapeutically effective amount.
