DiR (CyDiC is a near-infrared lipophilic carbocyanine fluorescence dye that incorporates into cellular plasma membranes and lipid bilayers. With absorption and emission maxima at50 nm and82 nm, it minimizes tissue autofluorescence and light attenuation. Membrane insertion allows durable fluorescence labeling of cells, liposomes, and extracellular vesicles without impairing cell viability, facilitating noninvasive whole-body optical imaging and tracking of cell homing, migration, and tissue biodistribution in vivo.

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).
