Popis: Rapid and catalyst-free hydrazone ligation reaction between ortho-halobenzaldehyde derivatives and peptide/protein hydrazides was observed at neutral pH and room temperature. 2-Chlorobenzaldehyde exhibited the fastest reaction and highest conversion rates among the series of ortho-halobenzaldehydes. The resulting hydrazone-containing bioconjugation products were also found to be fairly stable under experimental conditions. The new ligation strategy was successfully used for protein C-terminal labeling and should provide a practical approach for the modification of proteins.
