/ 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.

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.

Packing of toyopearl column for gel filtration: Results of this paper may be used in the selection of resins for further testing in biopharmaceutical protein purification process development. Publisher Summary Size exclusion fraactogel SEC is the predominant chromatographic technique for determining the molecular weight distribution of macromolecules. Yoshio Kato 19 Estimated H-index: Strong and weak cation-exchangers were compared for a number of chromatographic parameters, i.

Marina UrmannHeiner Graalfs. Unger University of MainzM. Earle Stellwagen 33 Estimated H-index: Djuro Josic 27 Estimated H-index: For lysozyme and aprotinin with pI above experimental pH, dependence of pH on retention was generally low, though some pronounced decrease of retention with increasing pH was observed for CM HyperZ.

Dependence of optimal packing velocity on column size. The separation mode is based on the differential penetration of molecules of different size and shape into the pores of the stationary phase.
John Westerlund 1 Estimated H-index: Jerker Porath 49 Estimated H-index: Influence of packing velocity on column performance. Chun-hua Cai 2 Estimated H-index: Montelaro Louisiana State University. Resins with good fracogel 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.
Thus, gels made for SEC should have controlled range of size of the pores. Size-exclusion chromatography of plasma proteins with high molecular masses.
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 MacroPrep resins. The most suited and widely distributed packings consist of glycidyl methacrylate copolymers, agarose, or composite gels containing dextran. Particle size distribution was determined by two independent methods, coulter counting and SEM pictures, with fair agreement.
