Fmoc-Val-Cit-PAB-OH

Fmoc-Val-Cit-PAB-OH is a useful heterobifunational linker for making Antibody-Drug-Conjugates (ADC) for targeting drug delivery. The Val-Cit will specifically be cleaved by catepsin B. As this enzyme is only present in the lysosome, the ADC payload will only be released in the cell. The azido group will react with DBCO, BCN or other Alkyne group through click chemistry. The PEG spacer increases aqueous solubility.
