Azido-PEG3-acid is a crosslinker containing an azide(N3) group with a carboxylic acid (CO2H). The terminal carboxylic acid is reactive with primary amine groups in the presence of activators (e.g. EDC, or HATU) forming a stable amide bond. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
