製品説明	FITC-Dextran (MW 4000) is a fluorescent probe for fluorescein isothiocyanate (FITC) dextran (Ex=495 nm; Em=525 nm). FITC-Dextran (MW 4000) can be used as a marker to reveal heat shock-induced cell damage and to study the early and late stages of apoptosis. FITC-Dextran (MW 4000) can also be used for cell permeability studies, such as blood-brain barrier permeability and determination of the extent of blood-brain barrier disruption^[1]^[2]^[3].
体外実験	Guide (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). 1. Solution preparation ^[2] 1.1 Preparation of storage solution Solvent: Ultrapure water Concentration: 10 mg/mL is recommended (e.g. weigh 10 mg FITC-Dextran (MW 4000) and dissolve in 1 mL solvent). Note: Sterilize by filtration through a 0.22 μm filter. 1.2 Preparation of working solution Dilute to 0.1 mg/mL with PBS or serum-free cell culture medium (optimized according to the experiment). Note: The working solution should be prepared and used immediately, and protected from light. 2. Cell staining Labeling of cells^[1]: For use with apoptotic HeLa cells and human peripheral blood mononuclear cells (PBMC) (viable HeLa and PBMC can not be stained by FITC-Dextran). 2.1 After cell apoptosis induction, suspend cells in 100 μL of culture medium, and mix with propidium iodide (PI) and FITC-Dextran (MW 4000) in a Q-prep tube. The final concentrations of PI and FITC-Dextran (MW 4000) are 7.5 μM and 1.13 μM, respectively. 2.2 Incubate the cells for 25 minutes at room temperature in the dark. 2.3 Collect 3 mL of labeled cell suspension and centrifuge at 500 g for 10 minutes. 2.4 Resuspend the pelleted cells in 1 mL of culture medium, and analyze by flow cytometry or fluorescence microscopy (PI: Ex = 500 nm, Em = 600 nm; FITC-Dextran (MW 4000): Ex = 495 nm, Em = 525 nm). Paracellular permeability measurement^[4] 1. Add FITC-dextran (0.1 mg/mL) to the basal media in the transwell chamber. 2. Collect media from the transwell insert after 15 min. 3. Measure the fluorescence signal (Ex = 485 nm, Em = 538 nm). 4. Calculate FITC-dextran concentration based on fluorescence intensity. 5. Calculate permeability.
