Additional Information and Online Ordering

HisPur Ni-NTA Superflow Agarose is a highly crosslinked, durable resin that does not compress at flow rates used for medium- or large-scale FPLC purifications. The resin holds up well to a variety of chemicals and pH values, and is compatible with common clean-in-place procedures. Compared to cobalt and other ligands used for immobilized metal affinity chromatography (IMAC), nickel provides greater capacity for His-tagged protein purification. HisPur Ni-NTA Superflow Agarose exhibits a high dynamic binding capacity across a range of flow rates, making it an excellent choice for larger scale purifications.

Highlights:

  • High capacity – binds greater than 20mg of His-tagged GFP per mL of resin at a linear flow rate of 300cm/hour

  • High purity – provides greater than 80% purity of eluted fractions when used to purify from lysates

  • Versatile – can be used to purify proteins under native and denaturing conditions

  • Robust – highly crosslinked beads tolerate linear flow rates up to 1200cm/hour

  • Compatible – maintains function in a wide variety of chemicals and pH conditions

  • Cost effective – competitively priced resin is stable through multiple cycles of cleaning and reuse

Frequently Asked Questions (FAQs)

Can ProBond or Ni-NTA beads be used for large-scale preparations?

ProBond and Ni-NTA beads can be used in FPLC columns. However, the beads can only withstand low pressure (~43.5 psi max).
What should the typical protein recovery be when using the Probond Purification System or Ni-NTA Purification system?

Both systems are qualified by purifying 2 mg of myoglobin protein on a column and performing a Bradford assay. Protein recovery must be 75% or higher.
What is the difference between HisPur Nickel Resin and HisPur Cobalt Resin?

Nickel has a higher affinity for histidines than does cobalt. It binds multiple histidines more tightly than cobalt, and requires more stringent conditions than is necessary for cobalt. The lower affinity of cobalt for multiple histidines typically results in less nonspecific binding of histidine-rich proteins that lack a his-tag compared to nickel resins.

HisPur Ni-NTA resin has a high capacity of up to 60 mg of 6xHis-tagged protein per milliliter. It is a versatile resin that can work under both native and denaturing conditions, and can also be used with a variety of lysis reagents and buffer additives.

HisPur Cobalt resin utilizes proprietary tetradentate chelating resin charged with cobalt. This system recovers highly purified protein with lower imidazole concentrations and has low metal leeching properties.
