Get to know how CESI-MS will allow you to quickly and accurately characterize protein therapeutics for attributes in a single method by downloading this discovery kit.

The Biologics Characterization and Discovery Kit Includes:

  • Executive Summary
  • Tech Note: A Unified Workflow for Monoclonal Antibody Charge Heterogeneity Purity, and Molecular Weight Analyses
  • Webinar: Biologics Characterization and Discovery by CESI-MS
  • Tech Note: CESI-MS Comparison of Tryptic Digests from Different Monoclonal Antibodies in an Assessment of Biosimilarity
  • Tech Note: Structural Characterization of ADCs by a Combination of Intact, Middle-up, and Bottom-up Approaches using CESI-MS

A Unified Workflow for Monoclonal Antibody Charge Heterogeneity Purity, and Molecular Weight Analyses
Discover how combining the unique separation capabilities of capillary zone electrophoresis (CZE) with the advantages of an MS-based detector provide high-resolution structural information and accurate molecular weight information. Using CESI-MS and stand-alone CE functionality of the CESI 8000 Plus system, researchers demonstrate powerful methods to characterize intact and reduced IgG forms.

CESI-MS Comparison of Tryptic Digests from Different Monoclonal Antibodies in an Assessment of Biosimilarity
Includes a summary of work recently published by the research group LSMIS at the University of Strasbourg. It focuses on how CESI-MS can be used to characterize and compare a marketed reference mAb with other biosimilar candidates. A CESI-MS protocol for biosimilarity studies of mAbs has been developed which highlights 100% amino acid sequence coverage & PTM “hot spot” mapping and ID.

Structural Characterization of Antibody-Drug Conjugates (ADCs) by a Combination of Intact, Middle-up and Bottom-up Approaches using CESI-MS
This tech note also summarizes work recently published by the research group at LSMIS. In this tech note, discover how CESI-MS can be used to characterize a gold standard cysteine-linked ADC, brentuximab vedotin. Want to learn more about highlighting DAR calculation under native conditions; drug distribution, drug location, 100% coverage and PTMs? It’s all here.
