DAF-FM is a reagent that is used to detect and quantify low concentrations of nitric oxide (NO). It is essentially nonfluorescent until it reacts with NO to form a fluorescent benzotriazole. DAF-FM fluorescence can be detected by any instrument that can detect fluorescein, including flow cytometers, microscopes, fluorescent microplate readers and fluorometers. DAF-FM Specifications: • Ex/Em of DAF-FM: ~495/515 nm • Lyophilized product should be dissolved using DMSO and then added to an aqueous buffer to create a working solution • DAF-FM diacetate is cell permeant and passively diffuses across...

Labeled calcium indicators are molecules that exhibit an increase in fluorescence upon binding Ca 2+ . Fluo-3 has been used to image the spatial dynamics of Ca 2+ signaling, in flow cytometry experiments involving photoactivation of caged chelators, second messengers, and neurotransmitters, and for cell-based pharmacological screening. Fluo-4 is an analog of fluo-3 with the two chlorine substituents replaced by fluorines, which results in increased fluorescence excitation at 488 nm and consequently higher fluorescence signal levels. Cells may be physically loaded with the cell-impermeant salt ...

Molecular Probes® CellTracker™ fluorescent probes freely pass through cell membranes and are converted to cell-impermeant reaction products. The cell-impermeant form is passed to daughter cells through several generations but is not transferred to adjacent cells in the population. Cells that are loaded with CellTracker™ probes are typically fluorescent and viable for at least 24 hours, making these probes excellent long-term cell tracers. Furthermore, the staining pattern can be fixed with formaldehyde or glutaraldehyde to allow long-term storage of the labeled cells or tissue, to facilitate s...

The lipophilic probe, FM™ 4-64FX exhibits low fluorescence in water but fluoresces intensely upon binding the outer leaf of the plasma membrane providing discrete plasma membrane staining. The binding is rapid and reversible and "FX" denotes that this analog is fixable with aldehyde-based fixatives. It is also an excellent reagent for identifying actively firing neurons and for investigating the mechanisms of activity-dependent vesicle cycling.
