Solvent & Solubility
DMSO : 50 mg/mL (80.03 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : ≥ 50 mg/mL (80.03 mM)
* "≥" 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 (sealed storage, away from moisture). 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.

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 (4.00 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 (4.00 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.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Protocol
Compounds used are: Ibutamoren mesylate (50 μg), octreotide (100 μg), and mGH (30 μg). Mice are give an initial ip injection (0.1 mL) of either saline, octreotide or mGH, followed 10 min later by an ip injection (0.1 mL) of either saline or Ibutamoren mesylate. Thus, the first study comprised of the following groups: saline/saline, saline/Ibutamoren mesylate, mGH/saline, mGH/Ibutamoren mesylate saline/saline, saline/Ibutamoren mesylate, mGH/saline, mGH/Ibutamoren mesylate, and the second study of: saline/saline, saline/Ibutamoren mesylate, octreotide/saline, octreotide/Ibutamoren mesylate. Additionally, a number of mice are injected ip with hypertonic saline (0.2 mL, 1.5 M) to serve as positive controls for the immunocytochemistry. Ninety minutes after injection animals are terminally anesthetized with sodium pentobarbitone (60 mg/kg, ip) and perfused transcardially with heparinized saline followed by 4% paraformaldehyde in 0.1mol/Lphosphate buffer (PB, pH 7.4). Brains are then removed and placed in the same solution for 24 h before being stored at− 80°C until processing. Coronal sections of forebrain (40 μM) are cut on a freezing microtome and placed in 0.1mol/LPB containing Triton X-100 (PB-T, pH 7.4). Sections are incubated for 24 h at 4°C in Ab-2 Fos antibody (rabbit polyclonal; 1:1000 in 1% normal sheep serum). The antibody-antigen complex is localized with a 1-h incubation in biotinylated anti-rabbit Ig, followed by a 1-h incubation in avidin, biotinylated horseradish peroxidase. The reaction product is visualized using a glucose oxidase-diaminobenzidine-nickel method, and Fos-like immunoreactivity is visualized as a dense purple-black precipitate restricted to the nucleus. The number of c-fos positive nuclei in the arcuate and periventricular nuclei (six to eight sections per mouse) are counted double-blind and a group mean calculated (mean±sem). Statistical analysis is performed by a two-way ANOVA followed by an all pairwise multiple comparison of data with significance taken as P < 0.05.
