Product Description
Poly(L-lactide)-b-poly(ethylene glycol)-vinylsulfone (PLLA-PEG-VS is a functional amphiphilic block copolymer with vinylsulfone (VS) group at the end of PEG. Vinylsulfone groups are useful for coupling thiol-containing targeting ligands via Michael addition. PLA-PEG-VS is used to prepare micelles or nanoparticles with vinylsulfone on the micelle surface for bioconjugation. Hydrophobic drugs is encapsulated in the PLA core for targeted drug delivery.
