Catalog No. : PSB-4304
Product Name : 4-Arm PEG-Aldehyde, MW 20k
Description :

PEG-aldehyde (propionaldehyde) 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. PEG aldehyde or ketone derivatives can be used in reversible PEGylation through its reaction with hydrazine or hydrazide forming a hydrolytic acyl hydrozone linkage. PEG butyraldehyde may be offered through custom synthesis.
