METHOD FOR PURIFICATION OF COMPLEMENT FACTOR H

摘要

A method for purification of complement Factor H from a complement Factor H containing source such as blood or blood plasma, in particular a caprylate precipitate of a Factor H containing source, which is e.g. obtained by addition of caprylate ions to fractions of blood or plasma, comprising the steps of: a)providing a Factor H containing source, in particular reconstitution of caprylate precipitate to provide a complement Factor H containing solution; b)performing a cation exchange chromatography in particular as first chromatographic step; c)performing an anion exchange chromatography; d)performing a hydroxyl apatite chromatography; e)followed by ultra/diafiltration to obtain a complement Factor H concentrate.
