The ER-Tracker™ Red dye is cell-permeant, live-cell stain that is highly selective for the endoplasmic reticulum (ER) that when stained using the protocol provided, the staining pattern is partially retained after fixation with formaldehyde. This stain consists of the green-fluorescent BODIPY® TR dye and glibenclamide. Glibenclamide (glyburide) binds to the sulphonylurea receptors of ATP-sensitive K + channels which are prominent on ER; the pharmacological activity of glibenclamide could potentially affect ER function. Variable expression of sulphonylurea receptors in some specialized cell typ...

Fluorescein di-β-D-galactopyranoside (FDG) is one of the most sensitive substrates for galactosidases. Nonfluorescent FDG is sequentially hydrolyzed by β-galactosidase, first to fluorescein monogalactoside (FMG) and then to highly fluorescent fluorescein. Enzyme-mediated hydorlysis of FDG can be followed by the increase in either absorbance or fluorescence.

DiI is a lipophilic membrane stain that diffuses laterally to stain the entire cell. It is weakly fluorescent until incorporated into membranes. This orange—red-fluorescent dye, which is spectrally similar to tetramethylrhodamine, is often used as a long-term tracer for neuronal and other cells. DiI is also available as a solution (V-22885), as a paste (N-22880) or as a solid (D-282).

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 ...

Nile red is used to localize and quantitate lipids, particularly neutral lipid droplets within cells. Nile red is almost nonfluorescent in water and other polar solvents but undergoes fluorescence enhancement and large absorption and emission blue shifts in nonpolar environments (excitation/emission maxima ~552/636 nm in methanol).
