LysoFP-NO2 is a turn-on fluorescent probe for carbon monoxide (CO) that localizes to the lysosome. When lysosomal CO is present, LysoFP-NO2 transforms into lysoFP-NH2, which is highly fluorescent. It is selective for CO over various reactive nitrogen, oxygen, and sulfur species. It displays excitation/emission maxima of 440/528 nm and is not cytotoxic to HepG2 cells for up to five hours at a concentration of 30 μM.
