HyperChrom Ni-NTA Excel Agarose

HyperChrom Ni-NTA Excel Agarose is an affinity chromatography medium that uses a highly cross-linked agarose gel as a matrix to incorporate a transition metal ion Ni²⁺ with tetracoordination, chemically coupled to a ligand of Nitrilotriacetic acid (NTA). It has a very stable octahedral structure, with nickel ions in the center of the octahedron to protect nickel ions from small molecules, is more stable, and can withstand harsh conditions such as reducing agents, denaturants or couplants at certain concentrations. In addition, due to the pressure resistance of the matrix, which can withstand pressures up to 0.3 MPa, the product can be used for industrial-scale protein purification, enabling purification of the protein of interest at relatively high flow rates. This chromatography medium uses the interaction between Ni²⁺ and the side chains of certain amino acids (mainly histidine) on proteins to enable the separation and purification of proteins with and without these amino acids, and with or without these amino acids.

Compared to HyperChrom Ni-NTA FF Agarose (PC2001) and HyperChrom Ni-NTA HP Agarose (PC2002), this product has the following advantages: (i) it has strong binding force with Ni²⁺, can tolerate 100 mM EDTA, and has better compatibility with buffers, (ii) has high alkali resistance, can withstand 0.5 M NaOH immersion for 48 h, does not need to remove nickel cleaning, avoids cross-contamination, saves time and efficiency.
