Histidine (His)-tag is widely used for affinity purification of recombinant proteins, but the yield and purity of expressed proteins are quite different. Little information is available about quantitative evaluation of this procedure. The objective of current study was to evaluate His-tag procedure ...
proteins with extremely high purity. When the highest purity is needed, this technique can be used as the first (capture) step in a multistep purification procedure. It is also suitable for purifying dual-tagged proteins with a histidine-tag at one end and a different tag at the other end...

(Chant et al., 2005) are some of the drawbacks of the interfering tag sequences. Sometimes these undesirable tag-induced failures can be resolved by the tag removal after purification via a specific proteolysis procedure using protease systems mainly composed ofTEV protease(Tobacco Etch Virus ...

The ligand can bind directly to either the protein of interest, for example, cAMP-resin for cAMP-binding PKA RIα and RIIβ proteins [19], or a tag that is covalently attached to the protein. Affinity chromatography is often the most robust purification procedure and is typically used in ...
A comparison of purification via Strep-Tactin® and Strep-Tactin®XT depicts two changes in the procedure. The first and second step (lysate application & wash) remain the same. But the elution and the regeneration streps are different for both systems. For elution from Strep-Tactin® des...
purification using a nickel column, performing grayscale scanning on imageJ to determine its purity, a single purified protein band was obtained with a purity exceeding 95% (Fig.1D). The presence of the recombinant protein with a His tag was confirmed by Western blotting using a monoclonal ...
