Solubility Data
Solubility (In Vitro)
DMSO : ~40 mg/mL (~90.99 mM)
Ethanol : ~4.4 mg/mL (~10.01 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.69 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (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 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume 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: ≥ 2.5 mg/mL (5.69 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 2.2748 mL 11.3742 mL 22.7485 mL
5 mM 0.4550 mL 2.2748 mL 4.5497 mL
10 mM 0.2275 mL 1.1374 mL 2.2748 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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
g/mol

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Reconstitution Calculator allows you to calculate the volume of solvent required to reconstitute your vial.

  • Enter the mass of the reagent and the desired reconstitution concentration as well as the correct units
  • Click the “Calculate” button
  • The answer appears in the Volume (to add to vial) box
In vivo Formulation Calculator (Clear solution)
Step 1: Enter information below (Recommended: An additional animal to make allowance for loss during the experiment)
Step 2: Enter in vivo formulation (This is only a calculator, not the exact formulation for a specific product. Please contact us first if there is no in vivo formulation in the solubility section.)

Calculation results

Working concentration mg/mL;

Method for preparing DMSO stock solution mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.

Method for preparing in vivo formulation:Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
             (2) Be sure to add the solvent(s) in order.

Biological Data
  • Ribonuclease protection assay to show synergy between TZ and inhibition of EGFR in the induction of CK13 and CK20 mRNA. A: NHU cells were treated for 24 hours in the presence or absence of TZ (1 μmol/L) and then for 4 days in the presence or absence of medium containing PD153035 (1 μmol/L). Total RNA was extracted and 5 μg was hybridized with 32P-labeled human CK13 and GAPDH riboprobes, electrophoresed, and quantified as described in the Materials and Methods. Band intensity was quantified by means of a phosphorimager and normalized against the GAPDH signal, which was included as an internal standard for loading efficiency. For comparison of relative expression, the cells treated with PD153035 and TZ cells were taken to be 1.0. Representative of three similar experiments. B: NHU cells were treated for 24 hours in the presence of TZ (1 μmol/L). Next, the cells were treated with PD153035 (1 μmol/L) and samples were taken at the times indicated. Controls that omitted PD153035 were included at days 2 and 6 to show the effect of TZ alone. Total RNA was extracted and 5 μg was hybridized with 32P-labeled human CK13, CK14, CK20, and GAPDH riboprobes. The samples were electrophoresed on a 5% polyacrylamide gel. Band intensity was quantified by means of a phosphorimager and normalized as described in A. The maximum level of expression was taken to be 1.0 and all of the other samples were expressed relative to the maximum. Representative of three similar experiments. C: NHU cells were pretreated for 1 hour with or without PA452, HX531, or HX603 at concentrations indicated, before incubation in the presence or absence of TZ and PA452, HX531, or HX603 for 24 hours, as indicated. Next, cells were either treated with or without PD153035 (1 μmol/L) and PA452, HX531, or HX603 for 4 days changing the medium and inhibitors every 2 days. Total RNA was extracted and 5 μg was hybridized to the CK13 riboprobe, electrophoresed, and band intensity was quantified by means of a phosphorimager and normalized as described in A. Expression levels of untreated NHU cells was taken to be 1.0 and all other samples were compared to the untreated cells.[2].
