MtoZ Biolabs provides ion exchange chromatography peptide purification service using the principle of ion exchange chromatography to achieve efficient separation and purification of charged peptides. This service is suitable for synthetic peptides, recombinant peptides, and complex peptide mixtures derived from biological samples. It effectively removes isomers, truncated peptides, and impurities to obtain target peptides with high purity and high recovery. The purified peptides are ideal for structural analysis, functional validation, and subsequent mass spectrometry detection in both research and pharmaceutical applications.
Principle of Ion Exchange Chromatography
Ion exchange chromatography (IEC) separates molecules based on their charge differences.
Separation Mechanism: The stationary phase carries charged groups that reversibly interact with oppositely charged peptides. By adjusting the pH or salt concentration of the mobile phase, target peptides can be gradually eluted.
Main Types: Includes cation exchange and anion exchange modes, suitable for peptides with different charge states.
Key Advantages: High selectivity, large loading capacity, excellent reproducibility, and minimal impact on peptide bioactivity.
