mPEG-b-POrn_m

Methoxy-poly(ethylene glycol)-block-Poly(L-ornithine) (mPEG-b-POrn) is a block material that covalently combines a defined-length PEG segment with ornithine residues with primary-amine side chains. Discrete chain lengths with different degrees of polymerization are available. Different segment compositions provide a structural basis for comparing hydrophilic–hydrophobic balance, side-chain presentation, or hydrophilic backbones. The methoxy end group defines the direction of chain-end capping or further conjugation. Solution conditions and target guests can be varied to compare dispersion, assembly, and subsequent functionalization.
