Properties
Description
PLLA(4k)-PEG(8k)-PLLA(4k) is a triblock copolymer consisting of a poly-L-lactic acid (PLLA) segment with a molecular weight of 4k, followed by a polyethylene glycol (PEG) segment with a molecular weight of 8k, and another PLLA segment of the same molecular weight at the end.
Molecular Weight
PLLA(4 kDa), PEG(8 kDa), PLLA(4 kDa)
Identity
Confirmed by NMR.
Applications
PLLA(4k)-PEG(8k)-PLLA(4k) can be used to prepare molecule carriers such as nanoparticles and microspheres. Active substances can be encapsulated in PLLA segments, while PEG segments prevent protein adsorption and immunorecognition.
