Epithalon white powder CAS 307297-39-8995 purity 99%

• • All operations must be completed in a standard sterile and dust-free laboratory environment. Operators need to wear professional protective equipment such as lab coat, sterile gloves and goggles. According to the experimental plan, take an appropriate amount of Epithalon lyophilized powder, add sterile water or PBS buffer solution slowly, mix gently by low-speed vortex or manual inversion, and let stand for several minutes until the powder is completely dissolved to form a transparent homogeneous solution. Prepare gradient concentration solutions according to experimental requirements, control experimental temperature, pH value and reaction conditions strictly to ensure accurate and repeatable experimental data. The prepared working solution is recommended to be used immediately to avoid activity attenuation caused by long-term placement.

• Epithalon lyophilized peptide powder is sensitive to high temperature, humidity, strong light and air oxidation. Unopened original products should be stored in a sealed, dry, dark and constant low-temperature environment at -20℃ for long-term preservation to maintain complete molecular structure and original experimental activity. Avoid placing in places with frequent temperature changes, high humidity and strong light exposure. After opening and sampling, the remaining powder must be fully sealed immediately to isolate air and moisture, and continue to be stored at low temperature to prevent moisture absorption, agglomeration and oxidation degradation. The reconstituted aqueous solution needs to be sealed and protected from light, stored at 2-8℃ refrigeration, and used up within three to five days. Repeated freezing and thawing is strictly prohibited. Under standard sealed and low-temperature storage conditions, the product shelf life is 24 months.
