Immobilized metal ion affinity chromatography (IMAC) resins are commonly used to purify his-tagged proteins, but also untagged recombinant or native proteins. The affinity chemistry is based on the coordination bonding between protein surface amino groups (histidine, tryptophan, cysteine, etc.) and transition metal ions (Ni+2, Co+2, etc.) immobilized on the resins. the IMAC resins are made from rigid, 80µm mono-sized polymethacrylate matrices that carry two different types of chelating ligands , iminodiacetic acid (IDA) or nitrilotriacetic acid (NTA). We offer Ni+2 charged IMAC resin products, UniIDA-80Ni and UniNTA-80Ni, as well as uncharged IMAC resins, UniIDA-80L and UniNTA-80, which can chelate with varied metal ions such as Cu2+, Ni2+, Zn2+ and Co2+.
