OSu-PEG4-VC-PAB-DMEA-Duocarmycin SA Size:1mg 6 SMILES [H][C@]12CS[C@@H](CCCCC(=O)NCCOCCOCCOCCOCCC(O)=O)[C@@]1([H])NC(=O)N2 Purity (HPLC)OSu PEG4 vc PAB DMEA Duocarmycin SA is a cleavable ADC druglinker conjugate that couples the potent antitumor antibiotic Duocarmycin SA to an OSu PEG4 vc PAB DMEA linker. The DNA? modifying agents such as duocarmycin are increasingly used in the development of antibody? drug conjugates (ADCs), where they serve as highly potent cytotoxic payloads. Designed for ADC research, this construct supports efficient antibody conjugation, PEG4? enhanced
