Dihydroethidium, also known as DHE, is a peroxide indicator. Dihydroethidium penetrates cell membranes to form a fluorescent protein complex with blue fluoresces. After entering the cells, Dihydroethidium is mainly localized in the cell membrane, cytoplasm and nucleus, and the staining effect is the strongest in the nucleus. Dihydroethidium produces inherent blue fluorescence with a maximum excitation wavelength of 370 nm and a maximum emission wavelength of 420 nm; after dehydrogenation, Dihydroethidium combines with RNA or DNA to produce red fluorescence with a maximum excitation wavelength of 300 nm and a maximum emission wavelength of 610 nm. 535 nm can also be used as the excitation wavelength for actual observation .

Calcein Blue AM is a cell staining agent. Calcein Blue AM serves as a substrate for intracellular esterases, which hydrolyze its acetoxymethyl (AM) ester group to convert the non-fluorescent reagent into fluorescent Calcein Blue. Calcein Blue AM passively penetrates the plasma membrane of both live and dead cells; it is converted into a polar fluorescent product and retained in the cytoplasm of live cells, whereas dead cells cannot retain the dye. Calcein Blue AM exhibits significant dye leakage, and its fluorescence intensity gradually decreases over time. Calcein Blue AM can be used for endpoint-based cell viability assays and short-term cell tracking experiments with a duration of no more than 4 hours.

Prodan is an environment-sensitive fluorescent probe used to investigate the polarity, fluidity, and structure of lipid membranes. Prodan exhibits environment-dependent excitation/emission wavelengths, with its wavelength range covering Ex = 360-410 nm and Em = 430-530 nm when in solvents, bound to DNA, located in lipid bilayers, or associated with proteins. Prodan can interact with the major groove of DNA, regions of lipid bilayers, and hydrophobic pockets of proteins. During phase transitions, Prodan localizes to different regions of the bilayer: the emission minimum is 430-440 nm in the gel phase, while it shifts to 480-500 nm in the liquid-crystalline phase or interdigitated gel phase. When bound to rigid hydrophobic sites of proteins, the emission peak of Prodan undergoes a blue shift and its fluorescence intensity increases .
