4-Arm PEG-NH2 (MW 5000) (GMP Like)

4-Arm PEG-NH2 (MW 5000) (GMP like) is 4-Arm PEG-NH2 produced by using GMP like guidelines. GMP like small molecules works appropriately as an auxiliary reagent for cell therapy manufacture. 4-Arm PEG-NH2 (MW 5000) (4-Arm PEG-amine (MW 5000) ) is a multi-arm PEG derivative with amine groups at each end of four arms attached to a pentaerythritol core. The reactive primary amine or NH2 groups can react rapidly with activated carboxylic acids such as NHS esters to form stable amide bonds[1].
