Chromstar FF Resins for Size Exclusion Chromatography

The Chromstar 4FF/6FF size exclusion chromatography resin is based on a highly cross-linked agarose-based matrix (4%/6% cross-linking ratio), which can separate different molecules by difference in molecular weight and molecular conformation. It is suitable for the separation and purification of various biomolecules, such as recombinant proteins, antibodies, nucleic acids, viruses, virus-like particles, and polysaccha rides.

Features of Chromstar FF Resins for Size Exclusion Chromatography

Chromstar 4FF/6FF size exclusion chromatography resin has excellent scale-up performance:

  • The highly cross-linked agarose-based matrix has excellent rigidity. This helps not only to reduce the requirements on bed height but also to achieve high process flow velocities under low back pressure, improving process efficiency.

  • The improved spherification process contributes to a smaller diffusion effect for better resolution.

  • High-flow velocity chromatography resin based on an agarose-based matrix.

  • With weak non-specific adsorption and good chemical stability.

  • Suitable for the separation of polysaccharides, recombinant proteins, viruses, and other large molecules.
