Overview
-
This kit for labeling any IgG1 antibody with monomethyl auristatin E (MMAE) using a valine-citruline p-aminobenzylcarbamate (VC-PAB) linker for early stage screening of your antibody.
This kit includes maleimide-activated VC-PAB-MMAE, which can be coupled directly to the IgG1 after reduction through alkylation in a single step (a method developed by Seattle Genetics: Sun et al. 2005, Bioconjugate Chem. 16, 1282-1290). The product is then purified to remove any unreacted drug.
• Drug Information
Name: Monomethyl auristatin E (MMAE) with MC-Val-Cit-PAB linkage
CAS number: 646502-53-6
Mechanism of action: Inhibits cell division by blocking the polymerization of tubulin. VC-PAB linker is stable in extracellular fluid, but cleaved by cathepsin B once inside the tumor cell, thus activating the antimitotic mechanism
Activities: Antioxidant, anti-inflammatory, anticancer, and insecticidal activities
• Requirement for Antibody
1. Preferably >90% pure by gel electrophoresis
2. Total amount: 0.1 mg or 1-3 mg of protein content as measured by UV.
• Key Features of this PerKit™
Offers a simple and easy way to label IgG1 with MMAE with minimum exposure to the toxin
Cathepsin B cleavable VC-PAB (Ref. Doronina et. al. 2008, Bioconjugate Chem. 19, 1960-1963)
Fast and easy preparation: 6 h preparation and <2 h hands-on time
All reagents and supplies included for preparation and purification
Easy to control the DAR if used together with the Thiol Assay Kit with Purification (Product#: CM90005)
Over 95% conjugated products (free of unreacted MMAE and less than 5% of unreacted antibody)Please contact us at for specific academic pricing.
