Event Overview:

Peptide mapping is considered the gold standard for the analysis of biopharmaceuticals. Classical analysis is performed through long workflows involving extensive sample handling and long liquid chromatography (LC-MS) analysis times.
The distinct advantages of short analysis times and unique separation mechanisms makes Capillary Electrophoresis (CE-MS) an attractive alternative for the peptide mapping analysis. Nevertheless, most existing sample preparation protocols are either incompatible with CE-MS analysis or require additional steps for salt removal that may increase sample handling.
In this webinar, we will present:

• An overview of the ZipChip Microchip CE-MS technology and its typical application space
• How to optimize CE-MS compatible sample preparation using a total workflow length of 2 hours
  • Data analysis will provide full sequence coverage and accurate quantitation of product quality attributes.
  • Wide applicability of the workflow to different IgG subclasses will be demonstrated.
• A panel discussion (Q&A) at the end

Key Learning Objectives:

• Microchip CE-MS technology, its capabilities, and typical application space
• How CE-MS technology can enhance peptide mapping throughput
• Coupling peptide mapping sample preparation of monoclonal antibodies to CE-MS analysis
• CE-MS analysis provides robust determination of quality attributes in less than 15 minutes.

Who Should Attend:

• Chemists
• Scientists
• Lab Managers

Sara Carillo
Bioanalytical Research Lead
National Institute for Bioprocessing Research and Training (NIBRT)

Dr. Sara Carillo completed her Ph.D. in Chemical Sciences in 2013 at the University of Naples “Federico II”. Under the guidance of Prof. Corsaro, she focused on the structural characterisation of polysaccharides and glyco-conjugates from Gram-negative bacteria via NMR and mass spectrometry techniques, focusing on the immunological properties and potentials of extremophiles endotoxins. After a period at the University College of Dublin, in 2015 she joined Dr. Jonathan Bones’s research group in NIBRT working on understanding of the effects of extractables and leachables from single-use bioreactors on CHO cells N-glycome and produced monoclonal antibodies. She is now working in NIBRT as Bioanalytical Research Lead and is mainly interested in the development of new analytical approaches to ensure a deeper and easier understanding of biomanufacturing processes and biopharmaceuticals’ structural complexity.
