MMAE (monomethyl auristatin E) is an antimitotic agent that binds tubulin and inhibits the assembly of microtubules. Mc-VC-PAB-MMAE is a thiol reactive derivative of MMAE that containing a cathepsin clevable valine-citruline p-aminobenzylcarbamate linkage. Mc-VC-PAB-MMAE is used to prepare antibody-drug conjugates, such as brentuximab vedotin (Seattle Genetics). This HRP-MMAE conjugate is designed with similar linker chemistry as ADC and is synthesized at CellMosaic for our customers' usage in Horseradish peroxidase (HRP) based assay. A long flexible PEG linker is also incorporated in the conjugate to retain the activity of HRP and MMAE binding.

The final conjugate is purified to obtain two MMAE-labeled HRP conjugates, and is lyophilized from PBS containing sugar-based stabilizer for easy shipping and storage. 

The product is sold as 1 vial of 0.5 mg (Cat# CM53210_0.5MG) or 4 vials of 0.5 mg (Cat# CM53210_2MG). For bulk orders, please contact us for a quote.
