Methoxypoly(ethylene glycol) Aldehyde (propionaldehyde)
mPEG-ALD
Catalog:CDN2019
Common Use | Methoxypoly(ethylene glycol) Aldehyde (propionaldehyde) (MPEG-ALD) 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. |
