DBCO-PEG4-Val-Cit-PAB-Exatecan includes an enzymatically cleavable peptide with an exatecan payload, and it is used in the synthesis of antibody-drug conjugates (ADCs). The Val-Cit will specifically be cleaved by Cathepsin B. The DBCO partakes in click chemistry reactions with azides. The PEG4 chain enhances the hydrophilicity of the compound. Reagent grade, for research purpose.
