Biological Activity
Swainsonine (0-40 μM; 12 h) shows antiproliferative activity in U251 and LN444 cells[2].
Swainsonine (30 μM; 12 h) induces apoptosis and cell cycle arrest at G2/M phase, and decreases the expression of CyclinD1 and CDK4 protein levels, increases the expression of p16 protein level[2].
Swainsonine (30 μM; 12 h) reduces glioma cell migration and invasion[2].

Solvent & Solubility
DMSO : 10 mg/mL (57.73 mM; Need ultrasonic and warming; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 4.17 mg/mL (24.07 mM; Need ultrasonic)
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.
