Evolution of the Monoclonal Antibody Purification Platform
Typical steps include:
• Protein A chromatography for capture of the product and removal of host cell-related impurities (host cell proteins and DNA). Though extremely efficient and effective,…

Enhancing Resins Addresses Purification Concerns
However, precipitation or size-exclusion chromatography (SEC) are not cost-effective when scaled up,” Deorkar says.
Affinity chromatography resins such as oligo(dT) can be…

A Closer Look at Affinity Ligands
Affinity chromatography is a separation method based on the specific binding interaction between an immobilized affinity ligand and its binding partner. The most common example in the realm of bioproc…

Continuous Manufacturing: A Changing Processing Paradigm
They also note that continuous capture typically requires sterile chromatography columns. “For downstream polishing steps, the infancy of multi-column chromatography systems is a limitation,” they add…

Digitalization: The Route to Biopharma 4.0
For chromatography, relating data from sensor with the CQAs of the process has been shown to improve CQA predictions with errors less than 5% (9). In two-column capture chromatography, dynamic control…

The Development and Application of a Monoclonal Antibody Purification Platform
In some cases, the broth was concentrated before the first chromatography step because of facility fit issues. Protein A chromatography was used in the initial capture step, where the antibody in cell…
