HisTALON Superflow Cartridges are FPLC cartridges prepacked with TALON Superflow Resin, which can withstand flow rates of 5–20 cm per min. This resin combines Superflow 6, a rigid, highly porous agarose derivative, with TALON. Columns prepacked with the resin can be used for efficiently purifying his-tagged proteins from a total soluble protein extract of bacterial, mammalian, or baculovirus-infected cells.

TALON Metal Affinity Resin is a durable immobilized metal affinity chromatography (IMAC) resin that has a remarkable affinity and specificity for his-tagged proteins. TALON resin is compatible with all commonly used IMAC reagents and allows protein purification under native or denaturing conditions.
TALON Metal Affinity Resin uses cobalt ions for purifying recombinant his-tagged proteins. TALON is a tetradentate chelator charged with cobalt, and is specific for his-tagged proteins. The TALON reactive core, containing cobalt, has strict requirements for the spatial positioning of histidines. Only adjacent histidines or specially positioned, neighboring histidines are able to bind the cobalt in this reactive core. In nickel-based resins (i.e., Ni-NTA Resin), these spatial requirements are less strict. Therefore, nickel-based resins are also able to bind histidines located in places other than the protein’s his-tag.
TALON Superflow Resin is specifically designed for quick and effective purification of his-tagged proteins at high flow rates and medium pressure (up to 150 psi)—it’s ideal for FPLC applications.
Overview
Choice of native or denaturing purification conditions
TALON resin retains its protein-binding specificity and yield under a variety of purification conditions. It is stable under both denaturing and native (nondenaturing) conditions. Deciding whether to use native or denaturing purification conditions depends on protein location, solubility, accessibility of the his tag, downstream applications, and preservation of biological activity.
Native conditions
Purifying a protein under native conditions is the most efficient way to preserve its biological activity, but requires that the protein be soluble. Advantages include:
- Eliminating the renaturation step at the end of the purification, saving time, and preventing significant loss of activity
- Retaining the ability to copurify enzyme subunits, cofactors, and associated proteins
Denaturing conditions
Because proteins that are overexpressed in prokaryotic systems sometimes form insoluble aggregates called inclusion bodies, you may need to purify proteins under denaturing conditions—using strong denaturants such as 6 M guanidinium or 8 M urea to enhance protein solubility. Advantages include:
- Complete solubilization of inclusion bodies and his-tagged proteins
- Improved binding to the matrix and reduced nonspecific binding, due to full exposure of the his tag
His-tagged proteins purified under denaturing conditions can be used directly in subsequent applications, or may need to be renatured and refolded. Protein renaturation and refolding can be performed prior to elution from the column. However, yields of recombinant proteins will be lower than under native conditions, because urea and guanidinium molecules compete with histidines for binding to metal.
Use of reducing agents
Purification with TALON resin may be carried out in the presence of β-mercaptoethanol, but not DTT or DTE, to preserve reduced sulfhydryl (-SH) groups that are important for the biological activity and structure of a given protein. TALON provides higher yields than Ni-NTA in the presence of β-mercaptoethanol.
