Chromstar® XL is an ion-exchange chromatography medium with ultra-high capacity and high resolution, which uses the difference in charge properties and amounts of different molecules under specific conditions to separate them. The chromatographic medium has good performance and can be used for the separation and purification of various biomolecules, such as recombinant proteins, antibodies, nucleic acids, viruses and virus-like particles, polysaccharides, etc.
Chromatography resin based on an improved agarose-based matrix with ultra-high binding capacity and high resolution. With both high binding capacity and high resolution, presenting excellent cost performance. With organic solvent resistance and good chemical stability.
Compared with traditional ion exchange chromatography media, Chromstar® XL shows better performance:
The improved Chromstar® base frame has stronger rigidity, so it can achieve higher process flow rate and improve process efficiency under lower back pressure.
By upgrading the ligand coupling method, with dextran extension arms, the dynamic binding capacity of the chromatography medium is improved.
Finer particle size improves the resolution of the chromatographic medium.
