Thermo Scientific™ HisPur™ Cobalt Spin Columns, 1 mL

Thermo Scientific™ HisPur™ Cobalt Spin Columns, 1 mL

Thermo Scientific HisPur Cobalt Spin Columns contain a tetradentate chelating agarose resin charged with divalent cobalt (Co2+) for obtaining high-purity his-tagged proteins with no metal contamination.

Features

• High purity—obtain more than 10 milligrams of pure His-tagged protein per milliliter of resin without optimizing imidazole washing conditions
• Specificity—cobalt-chelate coordination core binds fewer host protein contaminants, resulting in lower background than nickel resins
• Low metal leaching—no metal contamination in eluted histidine-tagged protein sample
• Versatility—purify proteins under native or denaturing conditions; compatible with Thermo Scientific Pierce Cell Lysis Reagents and a variety of buffer additives
• Cost effective—resin can be reused several times or discarded after single use
• Flexibility—available as bulk resin, kits, predispensed columns, chromatography cartridges and 96-well filter plates
