Carboxy-Amido-PEG5-Amine is a PEG reagent containing an amino (NH2) and a terminal carboxylic acid group. NH2 amine group is reactive with carboxylic acids in the presence of coupling reagents such as EDC, or directly with NHS esters, to form a stable amide bond. The hydrophilic PEG unit increases hydrophilicity. Reagent grade, for research purpose.
