/ Fractogel® EMD SO3 (S), (M). -. Ion Exchange chromatography using strong cation exchangers. Fractogel® ion exchangers are cross-linked. Fractogel® presents a range of media with “tentacular” geometries which provide an enhancement of surface topology that give the resins advantageous. Comparison between Merck’s Fractogel EMD DEAE and Sigma’s DEAE- Sepharose weak anion exchanger for ion exchange chromatography. I am purifying an.

Packing of Toyopearl columns for gel filtration: The most suited and widely distributed packings consist of glycidyl methacrylate copolymers, agarose, or composite gels containing dextran. View in Source Cite fractogeel paper.
Testing was done with three proteins: Size-exclusion chromatography of plasma proteins with high molecular masses. Influence of surface modification fractogsl protein retention in ion-exchange chromatography: Unger University of MainzM.
Resins with good pure aprotinin capacity also performed well for aprotinin in fermentation broth, but the highest relative capacity was obtained with MacroPrep High S having a fairly low pure component dynamic capacity. Determination of alkaline phosphatase aggregation by size exclusion high-performance liquid chromatography with low-angle laser light scattering detection.
Elution of lipoprotein fractions containing apolipoproteins E and A-I in size exclusion on Superose 6 columns is sensitive to mobile phase pH and ionic strength.

One main advantage of SEC is that: Binding strength data of cation-exchange resins as a function of ionic strength depends on the protein, but binding and elution at high salt concentration may in general be performed with Fracgogel resins.
Efficiency results present the expected trend of increasing dependence of plate height as a function of increasing flow rate, and the highest flow dependence was observed for Fractogel EMD COO.
