An EVOM™ Epithelial Voltohmmeter and chopstick electrodes (World Precision Instruments, UK) were used for the measurement of the electrical resistance of brain endothelial cell monolayers grown on Transwell® inserts. Monolayer TEER was calculated by subtracting the value of a blank Transwell® insert from the total resistance obtained for the endothelial monolayer and insert, and each TEER value was normalised for the surface area of the insert.
