  • Patent number: 7193056
    Abstract: The present invention relates to a process for purifying a hydrophobic or amphiphilic compound, by first mixing a starting material containing the hydrophobic or amphiphilic compound with a first polymeric material, water and at least one of a second polymeric material and a surfactant, wherein the first polymeric material and the second polymeric material and/or surfactant are immiscible in the resulting primary aqueous solution. The process further comprises maintaining the primary aqueous solution for a period of time sufficient for essentially separating the phases formed, and then removing the phase containing the main portion of the hydrophobic or amphiphilic compound and the second polymeric material and/or surfactant. The second polymeric material and/or surfactant are separated from the hydrophobic or amphiphilic compound, and subsequently recycled to the initial mixing step.

  • Patent number: 6559284
    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.

  • Patent number: 6506879
    Abstract: A substantially endotoxin-free ApoA or ApoE is produced by recombinant DNA technique, suitably in E. coli. Medicaments and methods for treatment of atherosclerosis or cardiovascular diseases employ ApoA or ApoE purified by a process comprising contacting a first aqueous solution comprising ApoA or ApoE and endotoxins with a matrix comprising an immobilized compound with an end group comprising two or three nitrogen atoms bonded to a carbon atom for attaching the endotoxins to the matrix, and subsequently treating the matrix comprising the immobilized compound with a second aqueous solution comprising a surfactant for releasing the ApoA or ApoE while the endotoxins remain attached to the matrix.
