Abstract
During recombinant production of asymmetric IgG-like bispecific antibodies (bsAbs), various by-products are often observed due to unbalanced chain expression and incorrect chain pairing. Among them, half antibody and homodimer are found with high frequency. In this work, with a case study we demonstrated that Capto MMC ImpRes mixed-mode chromatography can effectively remove these two by-products as well as antibody aggregates under optimized conditions. This makes MMC ImpRes a powerful tool for bsAb purification.
