Abstract

Chromatography resins having anionic exchange-hydrophobic mixed mode ligands, that are useful for purifying target biomolecules using anionic exchange (i.e., where the ligand is positively charged) and hydrophobic mixed mode chromatography. The chromatography resins allow for efficient purification of target biomolecules (e.g., recombinant proteins, antibodies, antibody-drug conjugates, or antibody derivatives including, but not limited to, antibody fragments and antibody fusions) from a sample, and have been found to be useful in purifying monomeric target biomolecules from aggregate target biomolecules. In an embodiment, the chromatography resins are useful for separating antibodies from one or more components (e.g., contaminants) in the sample.
