Method for identifying or analyzing polymer linkage sites on macromolecules using amino acid report binding

摘要

The aim of the invention is to provide a new method for identifying or analyzing polymer linkage sites on macromolecules using amino acid reporter binding. Another aim of this invention is to provide a compound FE ··· L ··· M, where M is a molecule consisting of proteins, peptides or polypeptides, FE is a functionalizing entity and L is a linking arm that is stable under physiological conditions but cleavable by specific and selective physical-chemical means.
