Green CMFDA
(Synonyms: 5-氯甲基荧光素二乙酸酯,5-Chloromethylfluorescein diacetate) 目录号 : GC43783绿色 CMFDA 作为一种非末端、非荧光探针,可以被活细胞常见的非特异性酯酶切割,产生荧光化合物荧光素,使用荧光显微镜可见。
Cas No.:136832-63-8
Sample solution is provided at 25 µL, 10mM.
Green CMFDA, as a non-terminal, non-fluorescent probe, can be cleaved by non-specific esterases common to living cells, producing a fluorescent compound, fluorescein, visible using a fluorescent microscope[1]. CMFDA is excited with a monochromator at 492 nm and is emissed at 548 nm[2].
In vitro, there was a a positive chondrogenic process of hBM-MSC labeled with 10 μM CellTracker? Green CMFDA, indicating these cells could differentiate into chondrogenic cells similarly to controlled non-labeled cells[3]. In vitro experiment it shown that 4 weeks after grafting stem cells, the green fluorescence of the originally CMFDA-labeled (10 μM) bladder epithelia was still detectable in all of the resulting glandular prostate epithelium[4].

Cell experiment [1]: | |
Cell lines |
platelets |
Preparation Method |
Samples of resting platelets and platelets activated by 100 µM ADP were adjusted to the platelet concentration of 3.5~3.8 × 108/L with autologous plasma, and incubated for 30 minutes at 37°C in 10 µM CMFDA. After incubation, the cytosolic esterase-induced fluorescence of platelets was measured by laser confocal microscopy and also photograph was taken. |
Reaction Conditions |
for 30 minutes at 37°C in 10 µM |
Applications |
The observation with laser confocal microscopy on CMFDA-stained platelets shows that nearly all the resting platelets release bright green fluorescence, whereas the ADP activated platelets release no or little fluorescence. |
Animal experiment [2]: | |
Animal models |
NOD/SCID or NOD/SCID/β2Mnull mice |
Preparation Method |
To determine the optimal time of BMDC injection in relation to bleo injury, 5 × 106 CMFDA-labeled BMDC were washed, resuspended in Hanks' buffer with heparin (50 U/ml), and administered via tail vein injection to NOD/SCID or NOD/SCID/β2Mnull mice 1, 2, 3, or 4 days post-bleo. |
Dosage form |
5 × 106 ;1, 2, 3, or 4 days |
Applications |
There was a 10- to 100-fold increase in the percentage of CMFDA+ cells seen in NOD/SCID/β2Mnull mice compared with NOD/SCID mice, with ∼0.04% positive cells seen when cells were infused at day 4 and mice were killed at day 7 after bleo. |
