His-tagged Fusion Protein Purification
We offer two ligands for the purification of His-tagged proteins: nickel (as Ni-NTA) and cobalt. Ni-NTA resins are recommended when maximum protein yield is desired. Cobalt resins are recommended when maximum protein purity is the goal. These magnetic beads and other resins are available in multiple formats to accommodate a variety of needs, from high-throughput screening, batch, pilot, and process purification. Superflow agarose resins have undergone extensive chemical characterization.
- More formats—magnetic beads, magnetic agarose, loose resin, spin columns and kits, FPLC cartridges, and 96-well filter plates enable fusion protein purification from microgram to kilogram scales.
- High performance—resins are designed to maximize protein yield and reduce background.
- Economical—pricing is similar to or better than other suppliers.

Featured product data
Purity of 6xHis-GFP on nickel resins. Aliquots (8 mL) of an E. coli over-expression lysate corresponding to approx. 16 mg 6xHis-GFP were loaded onto 1 mL columns (diameter = 0.7 cm) of two different Ni-NTA resins: Thermo Scientific HisPur Nickel Superflow Agarose and Qiagen™ Ni-NTA Superflow (Cat. No. 30410). Columns were washed with 10 mL (10 column volumes) of wash buffer containing 30 mM imidazole. Bound protein was eluted with 10 mL of elution buffer containing 300 mM imidazole. Fractions were collected at 1 mL intervals. Aliquots of load lysate (L), flow-through (FT), wash (W), and eluate (1 to 10) fractions were separated by SDS-PAGE and stained with Thermo Scientific Imperial Protein Stain (Cat. No. 24615). Purity of 6xHis-GFP across all elution fractions in each gel was determined by densitometry with Thermo Scientific myImageAnalysis Software (Cat. No. 62237).
