Zetadex-50 Superfine 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 Superfine 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 Superfine is set at 25 kD for proteins and 20 bp for nucleic acids. Purified biomolecules are not significantly diluted when processed using Zetadex-50 Superfine.
