FITC-Dextran (MW 10000) 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].
In Vitro	Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs). 1. Cell Marking (for cells undergoing apoptosis)^[1]: 1.1 Resuspend cells in culture medium and add Propidium Iodide (PI) and FITC-Dextran to a final concentration of 7.5 μM and 1.13 μM, respectively. 1.2 Incubate cells at room temperature in the dark for 25 minutes. 1.3 Centrifuge at 500 g for 10 minutes and discard the supernatant. 1.4 Resuspend cells in culture medium and analyze using flow cytometry or fluorescence microscopy (PI: Ex=500 nm, Em=600 nm; FITC-Dextran: Ex=495 nm, Em=525 nm). 2. Side-cell permeability assay^[4] 2.1 Add FITC-Dextran (0.1 mg/mL) to the basal medium in the upper chamber of the transwell. 2.2 Collect the medium from the lower chamber of the transwell after 15 minutes. 2.3 Measure the fluorescence signal (Ex=495 nm, Em=525 nm). 2.4 Calculate the FITC-Dextran concentration based on the fluorescence intensity. 2.5 Calculate the permeability.
