General description
Weak cation exchange Fractogel® EMD DMAE (M) resin in a convenient pre-packed 5ml column
Features and Benefits
MiniChrom Column Fractogel® DMAE (M), 5 ml enables:
- Excellent binding to large viruses and plasmid DNA
- Homogenous binding with high selectivity and purity
- Lower elution volumes for the highest purity levels
- Compatibility with 2.5 % (v/v) aqueous benzyl alcohol containing 150 mM NaCl storage solution
Due to the titration behavior, the ion exchange capacity can be used from pH 2 to pH 9.5. The separation of proteins is based on reversible electrostatic interactions between the negatively charged regions of the proteins′ surface and the support. Proteins are retained efficiently on Fractogel® EMD DEAE when the pH of the buffer is about 1 unit above their isoelectric points (pl).
The strength of the binding depends on the following:
- the buffer system
- pH value of the buffer which determines the surface charge of the protein
- the degree of the ionization of the functional groups of the exchanger
- the concentration of the counter ions
- the charge density on the support (protein binding capacity)
