S-Acetyl-PEG3-N3 (S-acetyl-PEG3-azide) is a versatile click linker used for bioconjugation, featuring a sulfur acetyl group and a terminal azide (N3) group connected by a linear PEG3 chain. This reagent can participate in copper-catalyzed azide-alkyne cycloaddition (CuAAC) with alkyne-containing molecules, forming stable linkages. Additionally, it enables strain-promoted alkyne-azide cycloaddition (SPAAC) with DBCO- or BCN-containing molecules, making it highly adaptable for various bioconjugation applications.
