Filter Medium

Gel filtration chromatography, also known as size-exclusion chromatography or molecular sieve chromatography, achieves separation and purification based on the varying elution rates of molecules of different sizes within the column.
The dextran gel has good stability, commonly used in desalting or buffer exchange. In general, gels with higher degree of cross-linking and smaller pores are suitable for separating bioproducts of low molecular weight, while gels with lower degree of cross-linking and larger pores are suitable forseparating bioproducts of high molecular weight.

  • HY-156045C
    Cross-linked dextran G 200 9041-36-5
    Cross-linked dextran G 200 is a hydrophilic gel based on molecular size exclusion and targeted macromolecular separation. Cross-linked dextran G 200 works through the gel permeation mechanism, and the cross-linked structure forms a three-dimensional network with a specific pore size, achieving separation based on the molecular hydrodynamic volume. Cross-linked dextran G 200 can be used to adjust the osmotic solute distribution coefficient and the ability to maintain osmotic equilibrium, such as in gel filtration chromatography for purification and analysis of biomacromolecules such as proteins and nucleic acids. Cross-linked dextran G 200 can also be used as a gel filtration filler (particle size range: 40-120 μm; globular protein separation range: 5-600 kDa).
