Gly3-VC-PAB-MMAE（Cat No.:I045859）is a cleavable antibody–drug conjugate (ADC) linker-payload system that couples a targeting antibody to monomethyl auristatin E (MMAE), a highly potent antimitotic agent. The tripeptide linker Gly-Gly-Gly (Gly3) enhances solubility and stability, while the valine–citrulline (VC) dipeptide is selectively cleaved by cathepsin B in lysosomes. The para-aminobenzyl (PAB) spacer ensures efficient drug release after cleavage. Once internalized, MMAE disrupts microtubule dynamics, inducing apoptosis in rapidly dividing cells. Gly3-VC-PAB-MMAE is widely used in cancer research for developing targeted ADC therapeutics.
