Description
Pre-hydrated Gel filtration matrix. Ready to use. For process purification of proteins and nucleic acids. Bead diameter: 50 – 150 µm (dry).
Zetadex-25 Medium 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-25 Medium 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-25 Medium is set at 5 kD for proteins and 10 bp for nucleic acids. Purified biomolecules are not significantly diluted when processed using Zetadex-25 Medium.
