Abstract:

A new type of pentamethine cyanine dye with bromo group at the central position Cy5-Br was designed and synthesized, and the structure is not reported as far as we know. Cy5-Br can identify SO2 derivatives bisulfite and sulfite with a good linear response. Furthermore, Cy5-Br has low cytotoxic to living cells, can localize in mitochondria, and image its bisulfite and sulfite ions concentration real-time change in living cells by the laser confocal fluorescence microscope.

Key words: Sulfite, Bisulfate ion, Mitochondria, Fluorescent imaging
