Solubility Data

Solubility (In Vitro)

DMSO : 100 mg/mL (116.56 mM)

Solubility (In Vivo)

Solubility in Formulation 1: ≥ 2.5 mg/mL (2.91 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	1.1656 mL	5.8281 mL	11.6562 mL
	5 mM	0.2331 mL	1.1656 mL	2.3312 mL
	10 mM	0.1166 mL	0.5828 mL	1.1656 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
