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).
