A Mab A Case Study In Bioprocess Development Patched -

The initial Protein A step used MabSelect SuRe™ resin. Loading at 30 g A Mab/L resin captured >99% of product, but elution at pH 3.5 caused significant aggregation (from 1.5% to 7%).

Mab-X requires two polishing steps due to a closely related charge variant (a deamidated isoform at Asn-55). A Mab A Case Study In Bioprocess Development

This case study on Monoclonal Antibody (mAb) development highlights how modern bioprocessing balances speed-to-market with high-quality yields. The Challenge The initial Protein A step used MabSelect SuRe™ resin

: Parameters like pH, dissolved oxygen, and initial viable cell density (iVCD) are studied in bioreactors to optimize growth and titer. This case study on Monoclonal Antibody (mAb) development

. Created by the CMC Biotech Working Group, it serves as a roadmap for systematically evaluating product quality, safety, and efficacy through process understanding. International Society for Pharmaceutical Engineering (ISPE) 1. Foundations: Defining the Product
