是一种用于活体染色的荧光探针，常与PI联用，用于检测细胞活力和细胞毒性等。Ex=494nm / Em=521nm

FDA是一种非荧光性疏水性荧光素衍生物，它可以穿透细胞膜进入细胞，通过细胞内酯酶催化水解二乙酸酯基团产生具有高强度的荧光产物荧光素。荧光分子在具有完整细胞膜的细胞内积累，因此这种绿色荧光可以作为一种细胞活力的标签。不具有完整细胞膜或者新陈代谢活性的细胞，不能在细胞内积累荧光产物，因此不能显现绿色荧光。FDA可以与染料PI联合使用，无活性的死细胞被PI着色，发出红色荧光；有活性的细胞PI无法着色，在FDA作用下，紧发出绿色荧光。这两种颜色可以很好的辨别死细胞与活细胞，与单一颜色检测相比，它提供了一种更为准确的活细胞定量检测方法。

In Vitro

Cell （KB cells；5μg/mL FDA；15s）

PI and FDA co-staining experiments evaluated the effect of PTT in vitro.   KB cells were cultured with Au NCs in 6-well plate at concentration of 100μg/mL based on the content of Au, and then irradiated by 660 nm laser with laser power density of 2 W/cm2 for different times of 0, 5, 10 and 15 min. FDA of 5μg/mL was used to stain the living cells, and the staining time was 15 s.   Meanwhile, PI of 5 μg/mL was used to stain the apoptosis cells, and the staining time was 15 min.

Cell（PC12 cell；10 μg/mL FDA；15 min）

PC12 cells were added to the 6-well plate with a density of 1 × 105 cells/well. Cells were cultured at 37 °C for 24 h with 5% CO2. The preincubated Aβ samples with or without 2.00 mg/mL ulvan were added to the cells and cultured for an additional 48 h. After the medium was gently aspirated with a pipet gun, cells with good adherence were incubated with 10 μg/mL FDA and 5 μg/mL PI for 15 min. Finally, the FDA/PI staining solution was removed, andn the cells were washed three times with PBS buffer and observed using a BX53 fluorescence microscope.

P. ternata seedling(Pinellia ternata root tip cell;  15 μg/mL FDA;  10min)

We accurately weigh 100 mg of fluorescein diacetate (FDA) (Solarbio, Beijing, China) and dissolved it in 4 mL of acetone to prepare a 25 mg·mL-1 mother liquor, which was stored away from light at -20 °C.  When in use, FDA storage solution was added to 0.65 mol·L-1 mannitol to obtain FDA dyeing solution in proportion.  10 mg of propidium iodide (PI) (Solarbio, China) was dissolved in 2 mL of 0.65 mol·L-1 mannitol to prepare a 5 mol·L-1 mother liquor.  The FDA (15 μg·mL-1) and PI (5 μg·mL-1) mixtures were used to treat P. ternata seedlings.  P. ternata seedlings were hydroponically cultured and treated with M-Pa-B for 1, 2, 3, and 4 h. After that, the root tips of seedlings were washed three times with deionized water and then dyed with the FDA-PI in the dark for 10 min. The excess dye was washed away thoroughly with deionized water after dyeing.  Ten root samples were collected from five individual plants at each time point.  A laser confocal scanning microscope was used for observation and photography.  The excitation and emission wavelengths are 488 nm and 630 nm, respectively.

Cell（L929 mouse fibroblast cells,stained with FDA and PI reagent at 1 mg/mL）

After 1, 4 days of culture, the medium was discarded, and L929 cells were washed with PBS and stained with FDA and PI reagent at 1 mg/mL.After incubating in the dark for 5 min, the cells were washed with PBS solution again.

Cell（MC3T3-E1 cell, Following incubation for 1, 3, and 5 days, live/dead cell staining experiments were conducted by using FDA and PI reagents）

a cell suspension with a density of 5 × 104 was carefully pipetted on the sterilized matrices that were placed in 24-well plates for cocultivation. Following incubation for 1, 3, and 5 days, live/dead cell staining experiments were conducted by using FDA and PI reagents. The stained cells were then observed and photographed on a laser scanning confocal microscope (LSCM) with a product model number of LSM 880.
