Fitc permeability

WebParacellular permeability of hydrophilic tracers can be monitored with compounds that are labelled fluorescently, such as dextrans. Herein, fluorescently labelled dextrans (4kD FITC dextran and 70 kD Rhodamine dextrans) are used as tracers since different sizes can be analysed by the same detection method; moreover, the use of both FITC and ... 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.
