Préparation de la solution mère
Préparer un 10 mM stock solution using DMSO. Par exemple: Dissolve 1 mg of Nile Red powder in 314.1 μL of DMSO.
Note:
- Unused stock solution is recommended to be aliquoted and stored at -20°C to avoid repeated freeze-thaw cycles.
- Moisture-absorbed DMSO significantly affects the solubility of the product. Please use freshly opened DMSO.
Preparation of Working Solution
Dilute the stock solution with an appropriate buffer (par exemple., serum-free culture medium or PBS) to prepare a working solution of 1-100 µM. Note:
- The final concentration of the working solution is recommended to be optimized according to different cell lines and experimental systems.
- If difficult to dissolve, ultrasound treatment can be used to facilitate dissolution.
Précautions
- Avoid using lipid substances in cell culture media. During staining incubation and observation, avoid strong light exposure to prevent fluorescence quenching.
- Pour votre sécurité et votre santé, wear lab coat and disposable gloves during operation.
- This product is for research use only. Do not use for pharmaceuticals, clinical diagnosis or treatment, food and cosmetics, etc.. Do not store in residential areas.
