Cell & Organelle Stains

DPX is a positively charged quencher that is often used with ANTS (90010) to study membrane fusion or permeability.

Ethidium bromide (EtBr) is a widely used nucleic acid gel stain although it is also a known potent mutagen. EtBr is an intercalating DNA-binding dye with little sequence preference.

Fluorescein biotin (5-((N-(5-(N-(6-(Biotinoyl)amino)hexanoyl)amino)pentyl)thioureidyl) fluorescein) can be used to detect and quantify biotin binding sites and the degree of biotinylation of proteins. Also see biotin-rhodamine 110 (80022) and biotin-4-fluorescein (90062).

Fluorescein-DHPE is a useful surface pH indicator, and has also been used for measuring lateral diffusion in membranes.

HM1-43 is a fixable, activity-dependent fluorescent nerve terminal probe.

Hoechst dyes are cell membrane-permeant, minor groove-binding blue fluorescent DNA stains. Hoechst dyes are widely used in cell cycle and apoptosis studies as nuclear counterstains.

Hydroxystilbamidine (also called Fluoro-Gold™) has been used extensively as a retrograde tracer for neurons and also a histochemical stain.

Hydroxystilbamidine (also called Fluoro-Gold™) has been used extensively as a retrograde tracer for neurons and also a histochemical stain. The 4% solution in deionized H₂O is a convenient, ready-made solution.

A fluorescent mitochondrial dye that can be used for ratiometric detection of mitochondrial potential changes.

A fluorescent mitochondrial dye that can be used for ratiometric detection of mitochondrial potential changes.

Like Lucifer Yellow CH, Lucifer Yellow Cadaverine can be used as a fixable fluorescent tracer. In addition, the dye can be used to conjugate to carboxylic acid groups.

This fluorescent biotin derivative is a useful tracer for studying neuronal morphology. The biotin portion of the molecule allows researchers to amplify the fluorescent signal using standard biotin-avidin or biotin-streptavidin biochemistry.

Lucifer Yellow CH lithium salt (LY CH lithium salt) is a widely used polar molecular tracer for studying neuronal morphology. The fluorescent molecule contains a carbohydrazide that allow the molecule to be aldehyde-fixable.

Lucifer Yellow CH lithium salt (LY CH lithium salt) is a widely used polar molecular tracer for studying neuronal morphology. The fluorescent molecule contains a carbohydrazide that allow the molecule to be aldehyde-fixable.

Lucifer Yellow CH potassium salt (LY CH potassium salt) is a widely used polar molecular tracer for studying neuronal morphology. The fluorescent molecule contains a carbohydrazide that allow the molecule to be aldehyde-fixable.

NBD C6-ceramide (6-((N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)hexanoyl)sphingosine) has been used for following sphingolipid metabolism in cells, and as a selective stain for the Golgi apparatus in live and fixed cells.
