PLL20k-g[3.5]-PEG5k

Poly-L-Lysine graft PEG or PEG-grafted-PLL(PLL-g-PEG,PEG-g-PLL)is is a random graft co-polymer with a poly(L-lysine) backbone and poly(ethylene glycol) side-chains.For surface modification,the PLL backbone interacts electrostatically with the substrate,while the side-chains extend from the surface to form a densely packed polymeric brush.
