CFSE Dyes chemical

Cat.No.S8269

Carboxyfluorescein succinimidyl ester (CFSE, 5(6)-Carboxyfluorescein diacetate succinimidyl ester, CFDA-SE, 5(6)-CFDA N-succinmidyl ester) is a fluorescent cell staining dye. This compound is frequently used in cell proliferation assay and motility assays. It is cell permeable and covalently couples, via its succinimidyl group, to intracellular molecules, notably, to intracellular lysine residues and other amine sources.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

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].
