/ 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.

Earle Stellwagen 33 Estimated H-index: The effect of competitive binding from yeast fermentation components on dynamic binding capacity of aprotinin was studied showing a significant decrease in binding capacity.

Size-exclusion chromatography of plasma proteins with high molecular masses. Thus, gels made for SEC should have controlled range of size of the pores. John Westerlund 1 Estimated H-index: Fracttogel size distribution was determined by two independent methods, coulter counting and SEM pictures, with fair agreement. Other Papers By First Author. Elution of lipoprotein fractions containing apolipoproteins E and A-I in size exclusion on Superose 6 columns is sensitive emv mobile phase pH and ionic strength.

Daniel Fracctogel 2 Estimated H-index: Results of this paper may be used in the selection of resins for further testing in biopharmaceutical protein purification process development. Chun-hua Cai 2 Estimated H-index: Testing was done with three proteins: Publisher Summary Size exclusion chromatography SEC is the predominant chromatographic technique for determining the molecular weight distribution of fractogdl.

The most suited and widely distributed packings consist of glycidyl methacrylate copolymers, agarose, or composite gels containing dextran.
