SuO-Glu-Val-Cit-PAB-MMAE consists a cleavable ADC linker (SuO-Glu-Val-Cit-PAB) and a potent tubulin inhibitor (MMAE). SuO-Glu-Val-Cit-PAB-MMAE can be used in the synthesis of antibody-drug conjugates (ADCs).In Vitro: ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
