Azido-PEG16-Hydrazide
Azido-PEG16-Hydrazide is a high-purity heterobifunctional PEG linker with an azide group for copper-catalyzed or strain-promoted click chemistry and a hydrazide group for conjugation with aldehydes or ketones. The PEG16 spacer specifically enhances water solubility, flexibility, and reduces steric hindrance, making it suitable for a wide range of bioconjugation applications.
Key Features
