8-Arm PEG-NH2 (MW 10000)

8-Arm PEG-NH2 (MW 10000) (8-Arm PEG-Amine (MW 10000) ) is a multi-arm PEG derivative, with each of its eight arms terminating in an amine group. The reactive primary amine or NH2 groups can rapidly react with activated carboxylic acids (such as NHS esters) to form stable amide bonds.
