PROTEIN RECOVERY BY CHROMATOGRAPHY FOLLOWED BY FILTRATION UPON A CHARGED LAYER |
摘要 |
The invention herein provides a method for recovering a polypeptide comprising exposing a composition comprising a polypeptide to a reagent which binds to, or modifies, the polypeptide, wherein the reagent is immobilized on a solid phase; and then passing the composition through a filter bearing a charge which is opposite to the charge of the reagent in the composition, so as to remove leached reagent from the composition.
