During purification many protein extracts tend to discolor an affinity gel during the loading step. The original color will return after the wash or elution step. If the color is still not changing strip and recharge the affinity gel with nickel. Wash with EDTA and recharge with Nickel solution.

General description
HIS-Select® Nickel Affinity Gel is an immobilized metal ion affinity chromatography (IMAC) product, used for the purification of His-tagged proteins. While the unique, non-charged, hydrophilic linkage of the proprietary quadridentate NTA chelate group to the beaded agarose charged with nickel ensures high selectivity for small to medium scale His-tag protein purification, it also results in reduced non-specific binding of other proteins. HIS-Select Nickel Affinity Gel is selective for recombinant proteins with His-tags and exhibits low non-specific binding of other proteins. The selectivity can be modulated with the inclusion of imidazole during chromatography.
Other Notes
It is also available with the EZview™ technology (Product Code E3528).
Physical form
1:1 suspension in a 20% ethanol solution
Preparation Note
HIS-Select Nickel Affinity Gel is stable for at least one year when stored properly. The HIS-Select Nickel Affinity Gel should be cleaned after each use and an antimicrobial agent such as 20% ethanol should be added to the storage buffer.

Can I use SDS with HIS-Select® Nickel Affinity Gel, Product P6611?
1 answer-
0.1% SDS has been used with some samples, with no adverse effects on the observed protein binding. However, SDS will effectively coat proteins and may block the binding to the column. It is probably very protein-specific and an SDS concentration that works for one protein may not work for another.

Can imidazole be used with HIS-Select® Nickel Affinity Gel, Product P6611?
1 answer-
For column chromatography, no more than 20 mM is suggested in the extract, equilibration, and wash buffers to prevent non-specific binding of proteins. No more than 250 mM is suggested for the elution buffers. Many proteins will elute with imidazole levels as low as 100 to 200 mM. For batch methods the imidazole concentration may have to be reduced or eliminated.When a protein is expressed at low levels, the presence of the imidazole limits the binding of the protein in the batch method but not when used in a column.

Why won't my recombinant protein with a histidine-containing tag bind to HIS-Select® Nickel Affinity Gel, Product P6611?
1 answer-
Verify the pH and composition of sample and equilibration buffers. Make sure there are no chelating or reducing agents present in the extraction buffer. If using the batch mode, remove imidazole. Run the affinity purification under denaturing conditions. Run a Western blot of the extract to verify that the recombinant protein is present.
