Unleashing the Power of Size Exclusion Chromatography (SEC) in Bioprocessing
Size Exclusion Chromatography (SEC), also known as gel filtration chromatography, is a cornerstone technique in the biopharmaceutical industry, prized for its ability to separate molecules based on their hydrodynamic size without denaturing them.
This non-destructive, high-resolution method plays a pivotal role across various stages of bioprocessing, including:
Protein characterization
Detection of aggregates and fragments
Formulation development and stability studies
Regulatory-compliant quality control
Why SEC? A Closer Look at Its Advantages
SEC offers several distinct advantages that make it indispensable for both research and manufacturing:
Preserves Molecular Integrity: Operates under mild conditions, maintaining structural fidelity of biomolecules.
High Resolution: Accurately differentiates between monomers, dimers, and aggregates.
Reproducibility: Ideal for consistent quantification and longitudinal analysis.
Compatibility: Works well with a range of common buffers and detection methods.
