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. |
