| 摘要 |
<p>The present invention relates to a substantially endotoxin-free apolipoprotein A (ApoA) or apolipoprotein E (ApoE) and a process for producing the same, by separating the endotoxins from the ApoA or ApoE, or variants or mixtures thereof, by contacting a first aqueous solution containing said ApoA or ApoE with a matrix containing an immobilized compound with an end group comprising two or three nitrogen atoms bonded to a carbon atom, and subsequently treating the matrix containing an immobilized compound with a second aqueous solution containing a surfactant, or by contacting a first aqueous solution containing said ApoA or ApoE with an anion-exchange matrix, and subsequently treating the anion-exchange matrix with a second aqueous solution containing a compound comprising two or three nitrogen atoms bonded to a carbon atom. The invention further relates to use of a matrix containing an immobilized compound comprising two or three nitrogen atoms bonded to a carbon atom and a solution containing a surfactant, or an anion-exchange matrix and a solution containing a compound comprising two or three nitrogen atoms bonded to a carbon atom, for removing endotoxins from aqueous solutions containing ApoA or ApoE, or variants or mixtures thereof. The thus produced ApoA or ApoE can be used for the manufacture of a medicament in the treatment of atherosclerosis and cardiovascular diseases, as well as in a method for treatment of atherosclerosis and cardiovascular diseases when administered in a therapeutically effective amount.</p> |
