                         This lyophilized powder is for laboratory research use only. Prepare the corresponding aqueous solvent or buffer according to your experimental requirements. Add the solvent slowly and mix gently until the powder is fully dissolved; do not shake vigorously to avoid foaming. The material is hygroscopic, so please complete the preparation quickly and minimize contact with air and moisture. It is recommended to prepare the solution immediately before use. Seal any remaining solution tightly and store at 2–8°C for short-term use. All operations must be performed by trained personnel in a standard laboratory environment.

                       Keep the vial tightly sealed at all times. For long-term storage, preserve the product in a dry, dark environment at -20°C and avoid repeated freeze-thaw cycles to maintain stability. After opening or reconstitution, store at 2–8°C and use within 3 months. Room temperature transportation is acceptable, but please transfer to the recommended storage conditions immediately upon receipt. The product is hygroscopic, so take extra care to protect it from moisture and high humidity.
