Biological Activity
Ioversol is a triiodinated, non-ionic organoiodine compound that functions as a radiographic contrast agent. Owing to its high iodine content, it absorbs X-ray radiation to enhance radiodensity and radio-opacity in vascular and parenchymal tissue during diagnostic X-ray imaging and computed tomography. As a low-osmolal non-ionic contrast medium, ioversol displays low chemotoxicity and minimal osmolality-related cell distortion in systemic circulation. [1]

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).
