Gel filtration matrix . Dry powder. For process purification of proteins and nucleic acids. Bead diameter: 100 – 300 µm (dry).
Zetadex-50 Coarse is a beaded composite size-exclusion gel developed by emp Biotech composed partially of cross-linked dextran. It exhibits high selectivity, high resolution and chemical stability.
Molecules purified with Zetadex-50 Coarse are separated according to size. Smaller molecules pass significantly slower through the column than larger molecules. Buffer and pH effects on resolution are minimal.
The size exclusion cut-off for Zetadex-50 Coarse is set at 25 kD for proteins and 20 bp for nucleic acids. Purified biomolecules are not significantly diluted when processed using Zetadex-50 Coarse.
