Solubility Data

Solubility (In Vitro)

DMSO :~100 mg/mL (~531.26 mM; with sonication (<80°C))

Solubility (In Vivo)

Solubility in Formulation 1: 3.75 mg/mL (19.92 mM) in 10% DMSO + 40% PEG300 + 5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one),clear solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared,you can add 100 μL of 37.5 mg/mL clear DMSO stock solution and add it to 400 μL PEG300 and mix well. Then add 50 μL Tween-80 to the above system and mix well. Then continue to add 450 μL of physiological saline to make up to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 3.75 mg/mL (19.92 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one),clear solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared,you can add 100 μL of 37.5 mg/mL clear DMSO stock solution and add it to 900 μL of 20% SBE-β-CD saline solution and mix well. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: 3.75 mg/mL (19.92 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one),clear solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared,you can add 100 μL of 37.5 mg/mL clear DMSO stock solution and add it to 900 μL corn oil and mix well.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	5.2565 mL	26.2826 mL	52.5652 mL

	10 mM	0.5257 mL	2.6283 mL	5.2565 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.
