Azido-PEG10-amine（Cat No.:R013332）is a heterobifunctional polyethylene glycol linker featuring a terminal azide and a primary amine separated by a ten-unit PEG spacer. The azide enables rapid, selective, and bioorthogonal click reactions with alkynes via CuAAC or copper-free SPAAC, supporting mild, catalyst-compatible conjugations. The amine reacts readily with NHS esters, activated carboxyls (EDC/NHS), isocyanates, epoxides, and aldehydes through reductive amination to form stable linkages. The PEG10 chain improves aqueous solubility, imparts flexibility, and minimizes steric hindrance, facilitating high coupling efficiency. Ideal for modular bioconjugation, probe and surface assembly, and drug-delivery research requiring orthogonal handles.
