Summary: https://www.creative-biolabs.com/adc/target-erbb2-37.htm This ADC product is comprised of an anti-ERBB2 monoclonal antibody (Trastuzumab) conjugated via a VC linker to Duostatin-3. The Duostatin-3 is targeted to certain cancers by immunerecognition and delivered into cancer cells via receptor mediated endocytosis. Within the cell, Duostatin-3 binds to tubulins, interrupts microtubule dynamics, and subsequently, induces cell death. Peptide linkers, belonging to Enzymatically cleavable linkers, combine greater systemic stability with rapid enzymatic release of the drug in the target cell. The scission of peptidic bonds relies on lysosomal proteolytic enzymes, which have very low activities in blood due to endogenous inhibitors and the unfavorably high pH value of blood. Duostatin-3 is an antimitotic agent that inhibits cell division by blocking of tubulin polymerization. Unlike vcMMAE, duostatin-3 cannot kill neighboring tumor cells when the drug is released from the anti
