Mass Spectrometry – an Essential Tool for Characterization of Monoclonal Antibodies during Development

03rd February 2016 | 9am EST | Dr Wei Xu & Dr Henry Shion |WATCH FOR FREE

Monoclonal antibodies (mAbs) represent a big portion of therapeutic proteins. Mass spectrometry (MS) coupled with modern separation technologies has become an essential tool in characterization of mAbs within the Quality by Design (QbD) paradigm during development. This Webinar will discuss the application of MS analysis in clone selection, optimization of fermentation conditions, development of purification and formulation. Specifically, simultaneously detect and monitor variants due to incomplete leader sequence processing, accurately determine afucosylation level of N-glycosylation, characterize host cell proteins (HCPs), identify degradation pathways and critical quality attributes (CQAs) will be discussed.
LinkWXDr. Wei Xu is a principal scientist in analytical method development at Merck Research Laboratories. He is an expert in characterization of therapeutic proteins using analytical methods based on mass spectrometry, UPLC and CE.  Dr. Xu has 10+ years’ experience in characterization of mAbs and other proteins while working in Merck, Regeneron and legacy Schering-Plough. Prior to that, he worked on the characterization of cannabinoid receptor 1 (CB1 receptor).  Dr. Xu received his Ph.D in pharmaceutical Sciences and MS in Statistics from the University of Connecticut.
