A new method for in-cell protein labeling was developed. This method employed a binding-induced nucleophilic reaction between the Cys-appended His-tag and the Ni(ii)-NTA containing an α-chloroacetamide. Using this method, not only labeling of His-tag fused proteins but also the detection of a protein-protein interaction was achieved inside living cells.
