What is NH2-PEG3-OH?
Description
(PEO)3-monoamine is a poly(ethylene oxide) (PEO) blocking reagent that prevents nonspecific adsorption of analytes in applications using covalent protein coupling such as ELISA. It reduces the adsorption of IgG when coated on carboxylic-terminated surfaces.
The Uses of NH2-PEG3-OH
(PEO)3-Mono-amine can be used as a novel improved cutting fluid.
