Fig. 5. TPM images of a fresh rat liver slice stained with the TPSNP-1 at a depth of 126 μm with a magnification of 60×. Images were acquired using 780 nm excitation and fluorescent emission windows: (A and B) The TPSNP-1 incubated without NaHS; (C and D) the TPSNP-1 incubated with NaHS (100 μM); (A and C) green = 440–540 nm; (B and D) red = 560–660 nm. Scale bars: 30 μm.
