Webb15 jan. 2024 · His-tag may need to be removed for certain applications, such as mass spectrometry or protein crystallization, with a protease, for example, His-3C protease [ 60 ]. A protease cleavage site can be built into the cloning vector that allows easy removal of the tag following protein purification. WebbThe purification of a protein via his-tagging is achieved through an interaction between varying divalent metal ions, like Ni 2+ (the predominantly used ion) and the basic …
WebbThe histidine-tag is small, so it usually does not have to be removed. Remove the tag if: it interferes with the function of the target protein the target protein needs to be in a native state (e.g., for structural studies) Cleave the tag using a protease that recognizes the protease recognition sequence in the target protein.
WebbElution and recovery of captured His-tagged protein from an IMAC column is accomplished by using a high concentration of imidazole (at least 200 mM), low pH (e.g., 0.1 M …
