SA-PEG-SA is a linear bifunctional PEG carboxylic acid reagent containing carboxyl groups at both ends of the molecular chain. A C3 ester bond exists between the PEG and the carboxyl group.SA-PEG-SA can react with amine groups by peptide coupling agents. It is generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated Counterparts.
