Figure 3. Time course of tritium labeled 3OC12-HSL levels associated with mammalian fibroblast and epithelial cells.

Figure 3

(A) NIH 3T3, A549, and MEF cells were incubated with a defined dose of 3H-3OC12-HSL for the times indicated. (B) A549 cells were incubated with either 3H-3OC12-HSL alone or 10 μM unlabeled 3OC12-HSL spiked with 3H-3OC12-HSL for the times indicated. In both cell types, levels of radioactivity associated with the medium and the cells were analyzed by liquid scintillation counting. The data are represented as the means±s.d.; n=4.
