Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Centrifuge the closed vial at 3000 rpm for 1–2 minutes to consolidate the powder at the bottom. For electrostatically charged powders, briefly warm the vial to room temperature and allow it to equilibrate before opening. Then add the appropriate solvent directly onto the powder and vortex before sonicating. Avoid tapping the vial vigorously, as this can generate fine powder aerosol.
Yes — TargetMol inhibitors can be used in cell-based and in vitro experiments. Prepare a DMSO stock, then dilute into cell culture medium to the desired working concentration, keeping DMSO ≤ 0.1% (v/v) to avoid solvent toxicity. Note that not all compounds have published data for every cell line or assay system; in such cases, perform a dose-response experiment with appropriate positive and vehicle controls to validate efficacy in your specific model.
