High-purity his-tagged protein purification with TALON resin

Cobalt resin products

TALON resin for his-tagged protein purification lets you prepare exceptionally pure his-tagged proteins from bacterial, mammalian, yeast, and baculovirus-infected cells, under native or denaturing conditions. TALON resin is an immobilized metal affinity chromatography (IMAC) resin charged with cobalt, which binds to his-tagged proteins with higher specificity than nickel-charged resins. As a result, TALON resin delivers his-tagged proteins of the highest purity. In addition, each cobalt ion is bound to the resin at four sites, resulting in low metal ion leakage. TALON resin is available in a variety of formats. Use the following tables to decide which one is best for your specific application.
