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.
Most small molecule inhibitors are not compatible with autoclaving (121 °C), which can cause thermal decomposition or loss of biological activity. For sterile cell-based experiments, filter-sterilize working solutions through a 0.2 µm membrane after dilution into aqueous buffer. Verify thermal stability in the DataSheet before applying any heat treatment.
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.
