WebFeb 7, 2024 · Using the same cell line and treated with 1, 10 and 100 ng/mL TNFα, study by Lopez-Ramirez et al. also observed a significant increase in paracellular permeability to 70 kD FITC-dextran at 24h upon treatment with10 ng/mL TNFα . The mechanism for LPS to increase permeability change is not well understood, since LPS did not cause … WebAfter treatment, a high molecular weight FITC-Dextran is added on top of the cells, allowing the fluorescent molecules to pass through the endothelial cell monolayer at a rate proportional to the monolayer’s permeability. The extent of permeability can be determined by measuring the fluorescence of the receiver plate well solution.
