Introduction: Nitrilotriacetic acid (NTA)-crosslinked-agarose resin consists of NTA groups covalently immobilized on agarose beads by stable ether linkages via a spacer arm. NTA is a tetradentate chelating agent forming octahedral coordination complex with divalent transition metal cations like Co2+ along with two water molecules occupied in cis manner. This ready to use resin, after loading with Co2+ is ideal for rapid purifications of His-tagged proteins.

Storage Temperature: 4°C
