Overview

This kit for antibody (IgG) labeling of monomethyl auristatin F (MMAF) with maleimidocaproyl linker (Mc) (a stable linkage). MMAF is a new antimitotic auristatin derivative with a charged C-terminal phenylalanine residue. The kit includes maleimide-activated MMAF (Mc-MMAF), which can be coupled directly to the antibody 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 purified to remove any unreacted drugs.
This kit provides materials to conjugate 1-3 mg of one (CM11422x1) or three (CM11422x3) antibody samples (IgG).
If you have a smaller amount of IgG, a non-IgG type antibody, or other customization needs, please select the customization radio button and/or fill out the information above.
