Confocal microscopy of P. aeruginosa incubated with fluorescein-labeled pre-elafin/trappin-2. Mid-logarithmic phase cultures of P. aeruginosa were incubated for 1 h at 37°C with fluorescein-labeled pre-elafin/trappin-2 and observed by confocal microscopy at 400 × magnification. From left to right, consecutive 0.2 μm sections of a fluorescent bacterial cell.
