Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 3.250mg/ml (9.94mM) Taking the 1 mL working solution as an example, add 50 μL of 65 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil

Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 0.450mg/ml (1.38mM) Taking the 1 mL working solution as an example, add 50 μL of 9 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)
