Features of Geldex PG Series Resins for Size Exclusion Chromatography

Geldex PG size Exclusion Chromatography Resins have excellent scale-up performance:

  • The improved Geldex matrix has excellent rigidity. This helps to achieve higher process flow velocities under low back pressure, improving process efficiency.

  • The improved Geldex matrix has great chemical resistance and is compatible with a wide range of buffer environments.

  • Finer particle sizes can provide better resolution.

  • High-resolution chromatography resin based on an improved agarose-based matrix.

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

  • Suitable for the separation of various biomolecules, including polypeptides, polysaccharides, recombinant proteins, nucleic acids, viruses, etc.
