Ion Chromatography-Based Charge Heterogeneity Analysis Service

    In biopharmaceutical processes, particularly for protein and antibody drugs, charge heterogeneity analysis is crucial for ensuring quality control of bioproducts. Interactions between molecules with different charge can significantly impact the bioactivity, immunogenicity, half-life, and charge stability of drugs, ultimately affecting their efficacy, stability, and safety. Ion chromatography (IC) is a widely recognized technique for analyzing charge heterogeneity in biomolecules by leveraging the charge adsorption interaction between charged molecules and ion exchange resins. IC can effectively separate molecules with varying charge states, enabling accurate identification and measurement of charge characteristics in samples. This technology is a key tool for developing and ensuring the quality of vaccines, antibody drugs, enzyme preparations, and other protein-based medications.
