Ni-IDA Resin A101272 5 x 5 ml

NI-IDA resin is a valuable tool for the purification of proteins with an affinity tag of six consecutive histidine residues. This histidine-metal ion interaction makes one-step purification possible for proteins from any expression system, under native or denaturing conditions. The His-tag sequence binds to Ni 2+ cations, which are immobilized onto a solid support using iminodiacetic acid groups (IDA). Impurities are removed and the purified His-tagged proteins can be eluted by imidazole or a reduced pH solution.
