Rapid Implementation of Novel Affinity Purification: Manufacture of Commercial-Scale Next-Generation Antibody Therapies

by , , , and

The rapid and cost-effective production of conventional monoclonal antibodies (MAbs) for clinical trials and commercial supply has contributed toward their wide adoption. Production processes have become more efficient because common purification processes are being used across structurally similar MAbs during key steps of process development and manufacturing. Such successful platform approaches can remove unwanted impurities and are stable across processing conditions, irrespective of the MAb being purified. In addition, they are readily available at the required volume to support large-scale…

Affinity Chromatography Applications with Single-Domain Antibodies

by , , , , and

Figure 1:  Current downstream processing strategies for recombinant proteins often require multiple chromatographic steps, which may lead to poor overall product yields. Product purification can be especially difficult when a target protein displays reduced stability, has isoforms or misprocessed variants, or needs to be purified from a complex mixture containing a high level of impurities. Through highly specific antibody–antigen based interactions, affinity chromatography brings significant technical advantage to these protein purification challenges. Developed to tackle such challenges, CaptureSelect™ technology is…

Increasing Purity and Yield in Biosimilar Production

by , and

Current downstream processing strategies for recombinant proteins often require multiple chromatographic steps, which may lead to poor overall yields. Product purification can be especially difficult when a target protein displays reduced stability, forms isoforms or misprocessed variants, or needs to be purified from a complex mixture containing a high degree of contaminants. One technology that has been developed to tackle such limitations is based on custom-made chromatography matrices containing camelid-based single-domain antibody fragments. With a molecular weight of only 12–15…

Novel Affinity Ligands Provide for Highly Selective Primary Capture

by , , and

    Downstream processing of biopharmaceuticals is costly and time-consuming, often involving multiple steps with significant time and energy expended on maximizing product quality and yield. Affinity chromatography is one of the simplest and most effective methods for purifying protein and peptide therapeutics, offering reduced process steps and therefore higher yields than nonaffinity methods can provide. Protein A is widely used for affinity purification of monoclonal antibodies (MAbs), Fc fragments, and Fc fusion proteins. But it is a challenge to…
