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:
A Unified Workflow for Monoclonal Antibody Charge Heterogeneity Purity, and Molecular Weight AnalysesDiscover 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 BiosimilarityIncludes 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-MSThis 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.

In drug discovery and development, Metabolite Identification (Met ID) plays a critical role in understanding biotransformation pathways, ensuring safety, and meeting regulatory requirements. Advanced mass spectrometry techniques have revolutionized this process, particularly through electron-based fragmentation methods such as Electron Activated Dissociation (EAD) and Electron Transfer Dissociation (ETD). While both techniques leverage electron interactions to generate informative fragment ions, they differ significantly in mechanism, performance, and suitability for Met ID workflows.
In analytical laboratories, performance is not optional. Whether supporting regulated pharmaceutical workflows, high-throughput CRO operations, clinical reporting, or food and environmental testing, your mass spectrometry and capillary electrophoresis systems are critical to productivity, compliance, and scientific confidence.
Naturally occurring toxins are an unavoidable reality of today’s global food supply, and among them, alkaloids represent one of the most analytically challenging and safety‑critical compound classes. Produced by plants as natural defence mechanisms, alkaloids can unintentionally enter food through contamination, co‑harvesting, or adulteration, posing serious risks to consumer health and regulatory compliance.
