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.

NBD C6-sphingomyelin (6-((N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino)hexanoyl)sphingosyl phosphocholine) has been used for following sphingolipid metabolism in cells.

NBD-PE (N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)-1,2-dihexadecanoyl-snglycero-3-phosphoethanolamine, triethylammonium salt) in combination with Rhodamine-DHPE (#60026) or Texas Red®-DHPE (#60027) has been used to study membrane fusion via fluorescence resonance energy transfer (FRET) (1-3). NBD-PE has also been used in photobleaching recovery measurement.

Neuro-DiI was developed at Biotium as an alternative to the widely used fluorescent membrane probe DiI. Neuro-DiI has structural features that may make the probe diffuse faster than DiI on cell membranes and also may result in a more stable labeling.

Neuro-DiI uniformly dissolved in vegetable oil in a formulation optimized for microinjection. Neuro-DiI was developed at Biotium as an alternative to the widely used fluorescent membrane probe DiI.

Biotium developed Neuro-DiO as a replacement for the green fluorescent DiO, which has been found to be difficult to use for neurons and cell suspension due to low solubility, tendency to form aggregates and slow lateral diffusion rate.

Neuro-DiO is a derivative of DiO and has spectral properties nearly identical to that of the latter. However, unlike DiO, Neuro-DiO is structurally more similar to DiI, which is known to be a much better lipophilic neuronal tracer than regular DiO.

Nile Red is a red fluorescent neutral lipid stain.

NAO is a green fluorescent mitochondrial dye whose staining is not dependent on mitochondrial membrane potential.

An improved alternative to 7-AAD showing less bleed-through fluorescence in the PE-Texas Red® channel. Ideal for selective detection of dead cells by flow cytometry.

The fluorescence of octadecyl rhodamine B in membranes is quenched at high dye concentration but is released at dilution. This property makes the dye useful for membrane fusion assays.
