生物活性

製品説明	Carboxyfluorescein succinimidyl ester (CFSE, 5(6)-Carboxyfluorescein diacetate succinimidyl ester, CFDA-SE, 5(6)-CFDA N-succinmidyl ester) is a fluorescent cell staining dye. CFSE is cell permeable and covalently couples, via its succinimidyl group, to intracellular molecules, notably, to intracellular lysine residues and other amine sources.
in vitro	Preparation of CFDA-SE working solution 1.1 Preparation of the stock solution Dissolve 1 mg of CFDA-SE in 0.1794 mL of DMSO to obtain 10 mM of CFSE. Note: It is recommended to store the stock solution at -20 ℃ or -80 ℃ away from light and avoid repetitive freeze-thaw cycles. 1.2 Preparation of this compound working solution Dilute the stock solution in serum-free cell culture medium or PBS to obtain 5-10 μM of this chemical working solution. Note: Please adjust the concentration of this compound working solution according to the actual situation. Cell staining 2.1 For suspension cells: Centrifuge at 1000 g at 4℃ for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time. For adherent cells: Discard the cell culture medium, and add trypsin to dissociate cells to make a single-cell suspension. Centrifuge at 1000 g at 4℃ for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time. 2.2 Add 1 mL of this compound working solution, and then incubate at room temperature for 30 minutes. 2.3 Centrifuge at 400 g at 4℃ for 3-4 minutes and then discard the supernatant. 2.4 Wash twice with PBS, 5 minutes each time. 2.5 Resuspend cells with serum-free cell culture medium or PBS, and then detect by fluorescence microscope or flow cytometer.
in vivo	In vivo labeling of cells with CFSE is feasible with virtually no toxic effect on the labeled or adjacent cells. It has advantages in relatively long-term migration studies as demonstrated by the recovery of T-cells in the peripheral lymphoid organs^[2].

	実験の流れ	The 5 mM CFDA-SE stock in DMSO is diluted to different concentrations(2 µM, 3 µM, 4 µM, 5 µM, 10 µM and 20 µM) in PBS with a total volume of 1 ml. After each cell line is harvested and washed three times with PBS, 1×10⁹ cells are added to equal volume of this compound with different concentrations and incubated at 37°C for 5, 6, 7, 8, 10 and 15 min with agitation. The labeling reaction is stopped for 1 min by adding an equal volume of heat inactivated fetal bovine serum. The CFDA-SE labeled cells are washed twice with PBS and recounted, and the cell concentration is adjusted to 6×104cells/ml in IMDM containing 10% FCS.
