DBCO-PEG4-alkyne is a four-unit PEG linker with non-cleavable properties, specifically designed for the synthesis of antibody-drug conjugates (ADCs)[1].
DBCO-(PEG)3-VC-PAB-MMAE is a chemical compound where monomethyl auristatin E (MMAE), a potent tubulin inhibitor acting as a toxin payload in antibody-drug conjugates, is conjugated to a DBCO-(PEG)3-vc-PAB linker.
