A Lysosome-Targetable and Two-Photon Fluorescent Probe for Monitoring Endogenous and Exogenous Nitric Oxide in Living Cells
摘要:
A lysosome-specific and two-photon fluorescent probe, Lyso-NINO, demonstrates high selectivity and sensitivity toward NO, lower cytotoxicity, and perfect lysosomal localization. With the aid of Lyso-NINO, the first capture of NO within lysosomes of macrophage cells has been achieved using both two-photon fluorescence microscopy and flow cytometry.

(PET) process to switch the fluorescence. The probe is able to selectively react with H2Se without interference from intracellular reactive species, and has been successfully used to image the H2Se content in lysosomes. Additionally, with the aid of Se-1, we demonstrated that lysosomal H2Se can be generated and can gradually accumulate in HepG2 cells under hypoxic conditions. These applications make Se-1
