Solubility
Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
| Solvent | Solubility & Note |
|---|---|
| DMSO |
100 mg/mL
(184.93 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.) |
| Ethanol | 100 mg/mL |
| Water | Insoluble |
| DMSO |
100 mg/mL
(184.93 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.) |
| Ethanol | 100 mg/mL |
| Water | Insoluble |
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
Storage
| Form | Storage Temp | Shelf Life |
|---|---|---|
| Powder | -20°C | 3 years |
| In Solvent | -80°C | 1 year |
| In Solvent | -20°C | 1 month |
