Abstract: Methods of purifying a heterodimeric protein (e.g., a bispecific antibody) from impurities through a series of chromatographic cycles are disclosed. In various embodiments, the pH of the elution buffer is increased with increasing cycles within the series to maintain minimal contamination with a binding impurity, and without significant loss of recovery of the heterodimeric protein.

Abstract: High resolution affinity chromatography combining affinity resolving and affinity capture processes using a single chromatography matrix results in improved resolution between closely related molecular species and significantly enhances overall product yield for large scale commercial production of heterodimeric proteins such as bispecific antibodies. Moreover, tankage and equipment requirements are reduced via the ability to reduce salt concentration, while increasing product purity and concentration, without the need for dilution, ultrafiltration or diafiltration.

Abstract: Embodiments of the present disclosure are directed to systems and methods for modulating pH in a mixture containing a polypeptide. The pH may be modulated for any suitable purpose, e.g., inactivating virus in the mixture. Methods may include eluting, from a chromatography column, a mixture (e.g., an eluate) having a pH greater than, e.g., 3.9 and less than, e.g., 8.5. Methods may further include one or more of measuring a protein concentration of the mixture and measuring a pH of the mixture. An amount of acid necessary to reduce the pH of the mixture to a target pH may then be calculated based on the protein concentration of the mixture, the pH of the mixture, or both. After an acid addition amount is calculated, a portion of acid may be added to the mixture, wherein the portion of acid is sufficient to achieve the target pH.
