What is Azadibenzocyclooctyne-PEG4-acid?
Description
DBCO-NHCO-PEG5-acid is an analog of DBCO-Acid with a hydrophilic PEG spacer arm, which improves water solubility. This reagent is a non-activated building block with enhanced solubility in aqueous media and can thus be used to derivatize amine-containing molecule through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions.
