Fig. 6. The two-photon fluorescence imaging of MGO in normal and diabetic mouse tissues. (A) Confocal images of five different mouse organ tissues (heart, liver, spleen, lung, and kidney) were obtained after incubation with NI-OPD (10 μM) for 2 h. The images represent one selected cross-section at a middle depth of about 50 μm. λex = 780 nm, collected at 420–480 nm. (B) Bar graphs representing the fluorescence intensity for each of the mouse organs. Scale bar: 100 μm.
