* In order to determine the efficacy of protein binding and recovery, tests were performed using a purified 75 kD protein in a static mode. All tests were carried out using Micro Bio-Spin columns packed with Profinity IMAC resin and eluted by centrifugation.
** Profinity IMAC binding capacities are unaffected with typical reagents used for histidine-tagged protein purification, up to the concentrations given.

Comparison of Maximum Operating Pressures

Comparison of maximum operating pressure for different IMAC resins. The pressure values shown are the estimated maximum operating pressures for each resin. Beyond these pressures, the column beds are seriously compressed and damaged. Resins were converted to 50% (v/v) slurry in 20 mM sodium phosphate buffer and packed in a 1.1 x 20 cm column to a bed height of 20 cm up to 42 psi (3 bar). Flow rates were then increased stepwise by 200 cm/hr and held for 2 min at each step. The pressure-flow curve for Profinity IMAC resin became nonlinear only at pressures above 109 psi (7.5 bar), the point defined as the intersection of the two tangents on the pressure-flow curve.

Profinity IMAC resin is an affinity chromatography support for the purification of recombinant histidine (His)-tagged proteins. Immobilized metal affinity chromatography (IMAC) is a powerful purification technique that relies on the affinity that His has for immobilized transition metals. Profinity IMAC resin, based on UNOsphere beads, contains iminodiacetic acid (IDA) as the chelating ligand for di- or trivalent metal ions. Its chemical structure allows highly selective binding of recombinant His-tagged proteins when charged with Ni2+ or other transition metals, such as Zn2+ or Cu2+.

Profinity IMAC resin offers high capacity at high flow rates. It can be used under either nondenaturing or denaturing conditions and is suitable for purification using liquid chromatographic instrumentation, gravity-flow columns, or spin columns.

The resin is available in two forms: uncharged and precharged with Ni2+. The uncharged form can be charged with the metal ion of your choice for even greater purification flexibility.

Features of Profinity IMAC resins include:

  • Optimal ligand density for higher purity of target protein
  • Superb mechanical strength
  • Excellent pressure-flow properties for high maximum operating pressures and high flow rates, which allow rapid purification as well as rapid column cleaning and re-equilibration
  • Stable from pH 1 to 14
  • Compatible with denaturing agents, detergents, and reducing agents
