Cell Surface & Membrane Dyes

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.

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.

Rhodamine-DHPE is a rhodamine-labeled glycerophosphoethanolamine lipid that has been used in membrane fusion assays.

Texas Red®-DHPE is a rhodamine-labeled glycerophosphoethanolamine lipid.

TRITC-DHPE  is a rhodamine-labeled glycerophosphoethanolamine lipid. DHPE conjugates of rhodamine dyes have been used in membrane fusion assays.
