Abstract

A new method for covalent labeling of a His-tag fused protein with a small reactive probe was developed; this method is based on the complementary interaction between the His-tag and Ni(ii)-NTA, which facilitates a nucleophilic reaction between a histidine residue of the tag and the electrophilic tosyl group of the Ni(ii)-NTA probe by the proximity effect.
