PROCESS FOR REDUCING THE CONCENTRATION OF FREE FC-MOIETIES IN A FLUID COMPRISING AN FC-CONTAINING PROTEIN

摘要

The invention relates to a process for reducing the concentration of free Fc-moieties in a fluid comprising an Fc-containing protein comprising a cation exchange chromatography step and to use of cation exchange chromatography for the reduction of the concentration of free Fc-moieties in a composition comprising an Fc-containing protein.
