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.
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.
