一般說明

Strong cation exchange Fractogel^® resin featuring the tentacle technology, for purification of basic and neutral proteins (e.g. antibodies) and peptides

特點和優勢

Fractogel^® EMD SO₃^- (M) enables:

• Increased binding strength at low pH
• High aggregate removal efficiency combined with high dynamic binding capacity
• 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 12. The separation of proteins is based on reversible electrostatic interactions between the surface′s positively charged regions and the support. Proteins are retained efficiently on Fractogel^® EMD SO₃^- (M) when the pH of the buffer is about 1 unit below 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 concentration of the counter ions
• the charge density on the support (protein binding capacity)
