cIEF Based Charge Heterogeneity Analysis Service

    Charge heterogeneity is a key attribute of biomolecules such as antibody, enzyme, and protein, affecting the molecule's stability, solubility, and biological activity. Changes of deamidation, oxidation, glycosylation, glycation, the N- or C-terminal, loss of three-dimensional structure, or reduction of disulfide bonds may lead to changes in charge heterogeneity. Since charge heterogeneity directly or indirectly affects the efficacy and safety of biomolecules, the analysis of charge heterogeneity occupies an important position in the research and development and production of biopharmaceuticals.

     

    Capillary isoelectric focusing (cIEF) is an advanced technique specifically used for analyzing charge heterogeneity. It employs a capillary as the medium, creating a pH gradient and applying an electric field to achieve a refined analysis of charge heterogeneity by migrating protein or peptide molecules to their isoelectric points. Thereby . cIEF is widely used in the analysis of protein isoelectric points, charge heterogeneity, and protein modifications due to its high-efficiency and high-resolution capability.
