DBCO-PEG4-Val-Cit-PAB functions as a cleavable ADC linker featuring a cathepsin-cleavable Val-Cit dipeptide, a PAB group, and a DBCO click chemistry handle. The benzylic alcohol on the PAB can be used to attach with reactive groups such as PNP for conjugation with drug payloads. DBCO is frequently used to conjugate with azides on target molecules. The PEG4 linker enhances the hydrophilicity of the molecule. Reagent grade, for research purpose.
