Modulated lysine variant species compositions and methods for producing and using the same

摘要

The instant invention relates to modulated lysine variant species compositions comprising a protein, e.g., an antibody, or antigen-binding portion thereof, and methods, e.g., cell culture and/or protein purification methods, for producing such modulated lysine variant species compositions. Methods for using such compositions to treat a disorder, e.g., a disorder in which TNFα is detrimental, are also provided.
