Principles of Capillary Electrophoresis Mass Spectrometry

CE-MS combines the principles of capillary electrophoresis (CE) and mass spectrometry (MS) to provide a comprehensive analysis of proteins. CE separates proteins based on their charge and size, while MS identifies and characterizes the separated species. This dual approach allows for the determination of molecular weight, charge, and other important characteristics of therapeutic proteins.

Applications in Therapeutic Protein Characterization

Structural Analysis

CE-MS enables the detailed structural analysis of therapeutic proteins, including the identification of post-translational modifications (PTMs),isoforms, and fragments. By providing information about the protein's primary, secondary, and tertiary structure, CE-MS helps researchers understand the relationship between protein structure and function.

Charge Heterogeneity Assessment

Therapeutic proteins often exhibit charge heterogeneity due to variations in PTMs, glycosylation, and other factors. CE-MS allows for the separation and identification of different charge variants, providing insights into the protein's charge distribution and its potential impact on biological activity.

Aggregation Analysis

Protein aggregation is a major concern in therapeutic protein development. CE-MS can detect and characterize protein aggregates, providing valuable information about their size, composition, and potential impact on efficacy and safety.

Impurity Analysis

CE-MS is a sensitive technique for the detection and identification of impurities in therapeutic protein samples. By separating and analyzing impurities from the target protein, CE-MS helps ensure the purity and homogeneity of the final product.

Advantages of Capillary Electrophoresis Mass Spectrometry

• High resolution and sensitivity
• Detailed structural and charge characterization
• Identification of PTMs, isoforms, and fragments
• Fast and efficient analysis
• Applicable to a wide range of therapeutic proteins

Capillary electrophoresis mass spectrometry is a transformative technology for therapeutic protein characterization. Its ability to provide comprehensive structural, functional, and conformational information empowers researchers and manufacturers to optimize protein development, ensure product quality, and advance the field of protein therapeutics.
