Solvent & Solubility
H2O : 100 mg/mL (211.53 mM; Need ultrasonic)
DMSO : ≥ 100 mg/mL (211.53 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.29 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.29 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
Working solution concentration: 0.22 mg/mL
This product has good water solubility, please refer to the measured solubility data in water/PBS/Saline for details.
Protocol
Male mice (specific-pathogen-free, 4 weeks of age) are divided into three groups. They are fed for 4 weeks with the CE2 diet containing one of three different antioxidants, 0.002 wt% DL-α-Tocopherol acetate (α-TA) (n=6), 0.02 wt% α-T (n=6) or 0.02 wt% α-TP(CD3) (n=7), per kilogram of diet. The mice are maintained under standardized conditions of light (7:00 AM to 7:00 PM), temperature (22°C), and humidity (70%). After 4 weeks, they are sacrificed under anesthesia with diethyl ether. The extracted brain, liver, heart, kidney, testis, and lung are homogenized in ice-cold 10 mM phosphate-buffered saline. Blood samples are collected in heparincontaining tubes. The samples are placed on ice immediately after collection. Plasma is obtained by centrifugation at 830 g for 5 min at 4°C and immediately subjected to analysis[2].
