Product description

4 arm-Polyethylene glycol-CHO, 4 arm-PEG-CHO, CHO-PEG-4 arm from ruixi 4-arm Poly(ethylene glycol) aldehyde (4-Arm PEG-CHO) from Advanced BioChemicals (ABC) are high quality multi-arm PEG derivatives with aldehyde at each terminal of the four arms that reacts with amine and N-terminal 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.The total molecular weight of 4-Arm PEGs is the sum of the molecular weights of all four arms.
