D-GsMTx4 (1 μM). The short-term effect of stretch in fASM cell proliferation. fASM cells on Flexcell plates were pretreated with piezo inhibitors for 1h and then were exposed to 5% static stretch with 5% oscillatory stretch (5% CPAP) with continuous presence of the inhibitors. Control cells were exposed to 5% oscillatory stretch only. Cells were harvested after 24h treatment and counted.

The long-term effect of stretch in fASM cell proliferation. fASM cells on Flexcell plates were pretreated with D-GsMTx4 (1 μM) for 1h and then were exposed to 5% static stretch with 5% oscillatory stretch (5% CPAP) with or without the inhibitors. Control cells were exposed to 5% oscillatory stretch only. Cells were harvested after 24h treatment and seeded into 96-well plates. After 3-day culture without stretch, cell proliferation was measured by CyQUANT assay.

溶剤 & 溶解度
DMSO : 100 mg/mL (Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL; 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.

3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
