Figure 2.

Widefield fluorescence micrographs of RAW 264.7 cells incubated with ACS-HNE (20 μM) before (–) or after (+) addition of human NE (HNE, 4 ng μL⁻¹, 100 μL); Excitation and emission wavelengths for ACS-HNE are 460–490 nm and 500–550 nm, respectively. The insert shows magnified sections of the corresponding fluorescence micrograph.
