Web12 okt. 2016 · Ion-Exchange Chromatography (IEC) allows for the separation of ionizable molecules on the basis of differences in charge properties. Its large sample-handling capacity, broad applicability (particularly to proteins and enzymes), moderate cost, powerful resolving ability, and ease of scale-up and automation have led to it becoming one of the … WebPerforming a Separation. This protocol can be used as a base from which to develop purification methods for proteins and peptides with affinity for metal ions: Metal-ion solution: 100 mM CuSO4. Binding buffer: 20 mM sodium phosphate, 500 mM NaCl, 10 mM imidazole, pH 7.4. Elution buffer: 20 mM sodium phosphate, 500 mM NaCl, 500 mM …
