Medchemexpress LLC N3-peg3-vc-pab-mmae | 99.1% | 1352.66 | C67H109N13O16 | 100 MG

N3-PEG3-vc-PAB-MMAE is an azide-functional drug-linker conjugate for antibody-drug conjugate (ADC) development, combining a PEG3 spacer, a valine-citrulline (vc) cleavable dipeptide linked to a para-aminobenzyl (PAB) self-immolative spacer, and the cytotoxic payload monomethyl auristatin E (MMAE). The compound supports bioconjugation via copper-catalyzed or strain-promoted azide-alkyne cycloaddition for linker optimization and ADC synthesis.

Azide handle enables copper-catalyzed and strain-promoted azide-alkyne cycloaddition for bioconjugation.
PEG3 spacer increases hydrophilicity and flexibility.
vc-PAB cleavable linker allows intracellular release of the payload.
Contains monomethyl auristatin E (MMAE), a potent tubulin inhibitor payload.
High reported purity suitable for ADC synthesis and analytical work.
Supplied in multiple pack sizes for research-scale applications.
