Product Description	Mal-PEG2-NH-Boc is a PEG derivative containing a maleimide group and a Boc protected amine group. The hydrophilic PEG spacer increases solubility in aqueous media. The protected amine can be deprotected by acidic conditions. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
