WebJan 10, 2024 · DAPI fluorescence intensity increases if attached to DNA compared to its unbound state. It is excited by UV-light with a maximum at 358 nm. Emission spectrum is broad and peaks at 461 nm. A weak fluorescence can also be detected for RNA binding. In this case, emission shifts to 500 nm. WebFluorescent probes for O 2·– Nitro-blue tetrazolium (NBT, 4) is a frequently used reagent for imaging the O 2·– for cellular development. NBT can be directly reduced by O 2·– to a water-insoluble precipitate with a blue emission, enabling in situ imaging and labeling of ROSs ( Fig. 3 ).
