E23: Intact and Top-Down Protein Characterization and Quantitation by Mass Spectrometry: Approaches for Pharmaceutical Drug Discovery, Development, and Bioanalysis

One-Day Course
Date to be announced; 8:30am – 5:00pm

Dr. John Kellie, GlaxoSmithKline, Collegeville, PA

Intact and top-down protein analysis by mass spectrometry (MS) is poised to play an increasing role in pharmaceutical industry in the areas of drug discovery (proteomics, target characterization), development & manufacturing (antibody characterization, quality attributes, mass analysis), and pre-clinical / clinical study support (biomarkers & biotherapeutic monitoring for in-life studies). This course will provide a background in sample processing, analysis by MS, and data interpretation and analysis for the many applications of intact protein MS in pharmaceutical industry.

Industry or CRO employees interested applying top-down and intact protein MS, academic scholars wishing to use or learn more about the techniques, and government employees interested the analytical workflows.

Dr. John Kellie is currently a Scientific Leader and GSK Fellow in the Bioanalysis, Immunogenicity, and Biomarkers group at GlaxoSmithKline. John received his B.S. in Biochemistry from Indiana University and his Ph.D. in Chemistry from Northwestern studying under Dr. Neil Kelleher. He was a Post-Doctoral Scientist at Eli Lilly and Company where he developed methods for intact protein quantitation of a Parkinson’s Disease biomarker from human brain tissue. At GSK, John utilizes mass spectrometry for development of novel bioanalytical methods for biotherapeutic & protein quantitation from pre-clinical and clinical samples, with a focus on intact protein and large mass quantitation for pharmacokinetics, catabolism, biotransformation, and product quality attribute support.
