Bioimaging of nitric oxide with fluorescent indicators based on the rhodamine chromophore.

H Kojima et al.

Analytical chemistry, 73(9), 1967-1973 (2001-05-17)

Diaminofluoresceins are widely used for detection and imaging of nitric oxide (NO), but for biological applications, they have the disadvantages that the fluorescence of the fluorescein chromophore is pH-sensitive and overlaps the autofluorescence of cells. We have developed a membrane-permeable
