S-Methyl DM1 Control Set for In Vitro Studies

Our S-Methyl DM1 Control Set is a ready-to-use solution for in vitro research, formulated to simplify your workflow and minimize handling risks of this potent cytotoxic agent. S-methyl DM1 is the primary cellular or liver metabolite of ADC or other conjugates prepared with DM1. DM1 (mertansine) is a thiol-containing derivative of maytansine. It binds to tubulin and inhibits the assembly of microtubules. DM1 is used to prepare antibody-drug conjugates, such as trastuzumab emtansine (abbreviated as T-DM1). DM1 is not very stable in aqueous solution and can be oxidized or dimerized. Our S-methyl DM1 is a high purity product that can serve as a control.

This control set contains 6 tubes of a 10 µM S-methyl DM1 solution in DMSO, a concentration suitable for most biological research and cell-based assays.

The 10 µM concentration is intentionally set within a safe, research-appropriate range for analytical studies, both quantitative and qualitative. Each tube is intended for a single experiment, enabling straightforward dilution (see Table 1 for suggested dilutions). The S-Methyl DM1 solution is pre-formulated and stable at room temperature, requiring no preparation before use or dilution.
