TSKgel Chelate-5PW, 10 µm, 1.000 Å, 7.5x75mm

TSKgel Chelate-5PW is based on a 100 nm (1000 Å) pore size polymethacrylate base material covalentely bonded with iminodiacetic acid (IDA) groups. Prior to chromatography, a metal ion, such as Zn2+, Ni2+ or Cu2+, is added to form a chelate with the IDA group. Peptides and proteins containing histidine residues will normally adsorb to these chelated ions at neutral pH. The retained compounds can be eluted with buffer containing imidazole or glycine.
