Abstract: Disclosed herein are compositions and methods for reducing the antigenicity of molecules. The antigenicity of a molecule may be reduced or eliminated by conjugating at least one branched polymer to the molecule to form a molecule-polymer conjugate. The branched polymer may include a backbone and a plurality of side chains, each side chain covalently attached to the backbone.
