Co-NTA XPure Agarose Resin is intended for preparative purification of histidine-tagged recombinant proteins from all prokaryotic and eukarotic expression systems. Co-NTA XPure Agarose Resin consists of highly cross-linked 6% agarose with an immobilized chelating group. The talon ligand is a tetra-dentate chelator charged with cobalt. Co-NTA XPure Agarose Resin offers enhanced selectivity for histidine-tagged proteins compared to nickel-charged medium. The XPure series of resins are made for large scale and fine purification using a high-performace liquid chromatography (HPLC) system.
