Medchemexpress LLC Dihydrofluorescein diacetate | 35340-49-9 | 98.5% | 418.40 g/mol | C24H18O7 | 1 ML
Dihydrofluorescein diacetate is a cell-permeable fluorimetric probe used to detect reactive oxygen species and assess oxidative stress in cell-free systems and live cells. Intracellular esterases remove the diacetate groups to generate the reduced fluorophore, which is oxidized by oxidants to produce a measurable fluorescent signal.
- Cell-permeable fluorimetric probe for oxidative stress measurements.
- Hydrolyzed by intracellular esterases to yield a fluorescent product.
- Applicable to both cell-free and cell-based assays.
- Supplied as a 10 mM stock solution in DMSO for convenient dosing.
- Excitation ~518 nm; emission ~616 nm for fluorescence detection.
- High purity (~98.5%) for reproducible experimental results.
- Store protected from light; solution stability: -80°C up to 6 months, -20°C up to 1 month.
