The invention relates to labelling agents containing a compound with a labelled molecule and a vinyl sulphone group. The invention also relates to the compounds, the method for obtaining them and the uses thereof in the marking of biomolecules and, more specifically, proteins.
The easy functionalization of tags and solid supports with the vinyl sulfone function is a valuable tool in omic sciences that allows their coupling with the amine and thiol groups present in the proteogenic residues of proteins, in mild and green conditions compatible with their biological function.
