Beschreibung
Zusammenfassung:	The invention pertains to methods of purifying fusion proteins, in particular TNFR:Fc fusion proteins. Methods disclosed herein can be used to produce highly pure TNFR:Fc fusion proteins (e.g., etanercept) having a biological activity by removing hard to separate product related impurities such as clipped and/or mis-fold/aggregated TNFR:Fc fusion proteins.
