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.
When solubility is listed as < 1 mg/mL, the compound dissolves to less than 1 mg per milliliter in water at 25 °C, pH 7.4. Such compounds require an organic co-solvent such as DMSO to prepare a concentrated stock, which is then diluted into aqueous assay buffer. For cell-based assays, keep the final DMSO concentration below 0.1% (v/v) to avoid solvent-induced cytotoxicity.
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.
