Nickel NTA HTC Agarose Resin has a binding capacity of ~60 mg/ml. In addition, it allows for purification of proteins under native or denaturing conditions. GoldBio Nickel Agarose works very well with the His-Tag Buffer Set.
NTA cross-linked Agarose resin consists of nitrilotriacetic acid groups ligated by stable ether linkages via a spacer arm. NTA is a tetravalent chelating agent, covalently coupled to cross-linked agarose beads, providing a higher specificity and lower ion leaching than IDA linked resins. NTA resins have also been shown to be more robust in the presence of higher concentrations of EDTA, but may require a higher imidazole concentration for protein elution. This resin is loaded with Ni 2+. The resulting, ready-to-use resin is ideal for rapid purifications of His-tagged proteins.
HTC beads are high throughput beads designed to meet the demand for industrial process separation. Their rigidity and mechanical resistance permits high flow rates, with good resolution in a minimum time frame, making these beads ideal for process-scale use. HTC beads are highly crosslinked 4% and 6% agarose matrices and have excellent physical and chromatographic qualities. They are autoclavable. These beads are an ideal support for the immobilization of ligands for Affinity Chromatography and base media support for producing IEX (Ion Exchange) and Hydrophobic interaction chromatography resins.
Binding Capacity: ≥60 mg/ml gel
Storage/Handling: Store at 4°C. Do not freeze.
Note: GoldBio recommends using Nickel NTA resins in the presence of elevated levels of reducing agents in order to ensure optimal purification of your target protein. Nickel IDA resins may show some discoloration in reaction with low levels of reducing agents but are still functional at low levels of reducing agents (≤5mM DTT).
