DBCO-PEG4-Propionic-Val-Cit-PAB

DBCO-PEG4-Propionic-Val-Cit-PAB is a click chemistry reagent and a cleavable 4-unit PEG ADC linker that incorporates a DBCO group. This group enables the compound to engage in strain-promoted alkyne-azide cycloaddition (SPAAC) with azide-bearing molecules. It is primarily utilized in the creation of antibody-drug conjugates (ADCs) [1].
