The His-tagged expression system is widely used in the production of recombinant proteins. The 6xHis tag on the expressed recombinant proteins allows for efficient coupling to Ni++ affinity resins and purification by single-step chromatography. The His-tag can be cleaved at sites recognized by enzymes such as thrombin and enterokinases to isolate the protein of interest.
Suitable for use in ELISA, Immunoprecipitation and Western Blot. Suitable for tracking the purification of proteins expressed in bacteria, yeast or insect cells. Other applications not tested.
Western Blot: 1:500-1:1000

|PAX6 transcription factor linked to 6-histidine tag (HHHHHH).|
|Purified by Protein G affinity chromatography.|
|Supplied as a liquid in PBS, pH 7.4, 0.09% sodium azide.|
|Recognizes proteins containing the motif H-H-H-H-H-H and proteins containing histidine tags. Suitable for tracking the purification of proteins expressed in bacteria, yeast or insect cells. , Recognizes all His tagged proteins so far tested. In Western Blot of bacterial extracts, does not crossreact with any endogenous products, though some crossreactivity may be seen with extracts of insect or mammalian cells. |
