Zusammenfassung:Provided herein are methods for purifying an anti-α4β7 integrin antibody, such as vedolizumab, from a liquid solution, e.g., from a mammalian cell culture clarified harvest. The invention relates, inter alia, to purification methods for controlling the amount of product-related substances and/or process-related impurities present in purified preparations of an anti-α4β7 integrin antibody, or antigen-binding fragment thereof, e.g., vedolizumab. Compositions comprising an anti-α4β7 antibody, and uses thereof to treat a disorder, are also provided.
