Properties
Description
PEI(2k)-PEG(5k)-PEI(2k) is a linear amphiphilic block copolymer with a polyethylene glycol (PEG) block and two poly(ethylene imine) (PEI) blocks. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
Molecular Weight
PEI(2 kDa), PEG(5 kDa), PEI(2 kDa)
Identity
Confirmed by NMR.
Applications
PEI(2k)-PEG(5k)-PEI(2k) can be used to encapsulate hydrophobic materials into hydrophilic carriers, thereby increasing their solubility and bioavailability.
