NH2-PEG3-NH2 (amino Polyethylene Glycol Amino) 929-75-9

NH2-PEG3-NH2 (amino polyethylene glycol amino) cas:929-75-9 is a linear bifunctional peg crosslinker with reactive primary amine or NH2 group, which can quickly react with activated carboxylic acids or carboxyl groups such as NHS esters to form stable amide bonds. PEG modification can improve solubility and stability, and reduce the immunogenicity of proteins and peptides. It can also inhibit the nonspecific binding of charged molecules on the modified surface.
