Mal-PEG8-Val-Cit-PAB-MMAE(CAT: I016628) is a cleavable antibody–drug conjugate (ADC) linker–payload system consisting of a maleimide (Mal) group, an eight-unit polyethylene glycol (PEG8) spacer, a valine–citrulline (Val-Cit) dipeptide linker, a self-immolative para-aminobenzyl (PAB) spacer, and the cytotoxic payload monomethyl auristatin E (MMAE). The maleimide enables stable conjugation to thiol groups on antibodies, while the Val-Cit-PAB sequence provides tumor-selective cleavage by cathepsin B, releasing active MMAE inside target cells. This design improves stability, solubility, and targeted cytotoxicity, making it a widely studied construct in cancer research, ADC development, and drug delivery studies aimed at enhancing therapeutic index and precision oncology.
