FAQ

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).

Administration Route	Formulation Type	Formulation Details	Solubility	Preparation Method
Oral Administration	Homogeneous suspension	CMC-NA	≥5mg/mL	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Oral Administration	Homogeneous suspension	CMC-NA	≥5mg/mL	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Injection	Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	2.000mg/mL (5.68mM)	Taking the 1 mL working solution as an example, add 50 μL of 40 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.
