/ 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.

Particle size distribution was determined by two independent methods, coulter counting and SEM pictures, with fair agreement. Dependence of optimal packing velocity on column size.

Cation-exchange chromatography of monoclonal antibodies: 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. Characterisation of a novel stationary phase designed for production-scale purification mabs [IF: John Westerlund 1 Estimated H-index: Yoshio Kato 19 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.
