Development of effective purification process for bispecifics using affinity capture and mix-mode polishing chromatography

KBI Biopharma and JSR Life Sciences have developed processes for the purification of BsAbs utilizing Amsphere A3 affinity chromatography followed by two polishing steps to eliminate undesirable homodimers and other impurities.

Amsphere A3’s superior binding capacity, resin lifetime, and caustic stability can provide a cost effective, supply-chain stable purification strategy when paired with well-designed polishing steps. In addition to A3 affinity capture, KBI’s platform BsAb purification process includes mixed-mode anion exchange and cation exchange to eliminate homodimeric impurities.

OnDemand Webinar

Effective Cleaning and Sanitization of a Protein A Resin

This webinar will discuss the efficacy of cleaning off proteinaceous fouling from a methacrylate-based Protein A resin for an extensive range of CIP protocols. Furthermore, an in-depth statistical analysis is presented on the cleaning effects of both NaOH concentration and contact time. Together with the impact on DBC retention, this can assist process engineers in developing intensified cleaning strategies. Finally, guidelines are presented for using peracetic acid to sanitize the resin in the event of contamination with spore-forming bacteria.
