Figure 2From: Recent advances in hydrogen peroxide imaging for biological applicationsFluorescence imaging of intracellular H 2 O 2 production using fluorescence probe PF6-AM (green). (A) Mechanism of Chemoselective H2O2 PF6-AM. (B) TPF imaging of H2O2 in astrocytes, fluorescence excited with a 770Â nm Ti:sapphire laser. (C) Confocal microscopy of H2O2 in same astrocytes imaged in panel B, fluorescence excited with a 488Â nm laser. The nuclei were stained with Hoechst 33342 (blue).Back to article page
