S-methyl DM4 is the primary cellular or liver metabolite of ADC or other conjugates prepared with DM4. DM4 (ravtansine) is a semisynthetic analogue of maytansine with a C3 ester side chain bearing a dimethyl hindered thiol substituent. It binds to tubulin and inhibits the assembly of microtubules. DM4 is used to prepare antibody-drug conjugates. DM4 is not very stable in aqueous solution and can be oxidized or dimerized. CellMosaic’s S-methyl DM4 is a high purity product that can serve as a standard for HPLC and LC-MS/MS analysis. The product is formulated in DMSO solution, quantified by UV/HPLC using DM1 as standard/calibrator at 252 nm, and ready to use after dilution. Although S-methyl DM4 inhibits polymerization weaker than DM4, it can also be used as a stable control for the ADC studies instead of DM4.
The product is sold as 1 vial of 1 mg (126 uL x 10 mM). If you would like to buy multiple vials, please check our Bulk Pricing:Buy in bulk and save
