FIG. 3.

Bar graph showing that treatment with human recombinant RANTES did not significantly affect the transepithelial resistance (TER) of T84 monolayers (mean ± SEM; n = 3 to 6 monolayers). T84 cells were grown to confluence (i.e., >1,000 Ω/cm²) on semipermeable filter supports (Costar Inc.), and then RANTES was added to the basolateral well of the culture plate and transepithelial resistance was subsequently monitored at the specified intervals by using chopstick electrodes and a voltmeter (Millipore, Bedford, Mass.) (11).
