Additional Information and Online Ordering

HisPur Cobalt Superflow Agarose is a highly crosslinked, durable resin that does not compress at flow rates used for medium- to 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 nickel and other ligands commonly used for immobilized metal affinity chromatography (IMAC), cobalt provides greater specificity for His-tagged protein purification. The specific binding of HisPur Cobalt Superflow Agarose results in purer elution fractions, reducing the need for extra polishing steps.

Highlights:

  • Robust – highly crosslinked 6% agarose Superflow beaded support tolerates linear flow rates up to 1200cm/hour with minimal leaching of cobalt due to a tetradentate chelator

  • High yields – binds 20mg of 6xHis-GFP per mL of resin at a linear flow rate of 150cm/hour, can bind greater than 30mg per mL of resin depending on flow rate

  • High purity – specificity of cobalt binding to histidine-tag generally results in elution fractions with less than 10% contamination of non-specific proteins

  • Compatible – maintains function after exposure to a wide variety of chemicals and pH values

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

Frequently Asked Questions (FAQs)

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.
