生物活性 | 5-Carboxyfluorescein diacetate N-succinimidyl ester is a cell permeable dye (Ex=492 nm, Em=517 nm). 5-Carboxyfluorescein diacetate N-succinimidyl ester can label cells by covalently binding to intracellular molecules. 5-Carboxyfluorescein diacetate N-succinimidyl ester is used to track lymphocyte migration and proliferation[1]. |
体外研究 (In Vitro) | Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs)[1]. 1. Dilute the stock solution in PBS (to give a 50 μM solution). 2. Add 110 μL of this solution per milliliter of cells (to give a final concentration of5 μM) and mix rapidly. 3. After5 minat room temperature, add 10 vol of PBS containing 5% FBS. 4. Centrifuge cells 5 min at 300 ×g, 20 ℃. 5. Remove the supernatant, and wash threetimes, each time by resuspending in 10 vol PBS containing 5% FBS. 6. Centrifuge cells 5 min at 300 × g, 20 ℃, and remove the supernatant. Note: Labeling occurs rapidly, and it is essential that the tracker is dispersed as evenly and quickly as possible so that cells are uniformly labeled.
