Aldehyde reacts with amine and N-terminal of peptide and protein to form an imine containing a C=N double bond, which can be further reduced to a more stable C-N bond. PEG aldehyde or ketone derivatives can be used in reversible PEGylation through its reaction with hydrazine or hydrazide forming a hydrolytic acyl hydrazone linkage. PEG butyraldehyde may be offered through custom synthesis.  甄准免费电话 400-002-3832
