Azido-PEG3-NHS ester（Cat No.:I015831）is a heterobifunctional crosslinker designed for efficient and selective bioconjugation. It combines an azide group, enabling copper-catalyzed or strain-promoted click chemistry, with an NHS ester that reacts readily with primary amines on proteins, peptides, or other biomolecules. The PEG3 spacer enhances hydrophilicity, minimizes steric hindrance, and improves accessibility in complex biological environments. This balance of reactivity and solubility makes it an excellent tool for protein labeling, drug delivery systems, biomaterials development, and diagnostic applications where precise and stable molecular linkages are essential for reliable experimental outcomes.
