General description

Hydroxystilbamidine bis (methanesulfonate), also known as Fluoro-Gold, is a retrograde fluorescent tracer. Chemically, Hydroxystilbamidine is a weak base and can cross cell membranes in its uncharged form.[1]

A few properties of Hydroxystilbamidine bis (methanesulfonate) are:[2]

Intense Fluorescence.
Extensive filling of dendrites.
High Resistance to fading.
No uptake by undamaged fibers.
No diffusion from labelled cells.
Highly compatible with other neuro-histochemical techniques.

Application

Hydroxystilbamidine bis(methanesulfonate), a fluorescent retrograde tracer (axonal transport), is used for neural mapping in microanatomical research.

Hydroxystilbamidine bis (methanesulfonate) or Fluoro-Gold (FG) is used to label neurons and investigate the early effects of hearing loss.[3] It is used to study morphological features of extensive axonal projections within the CNS by labelling the cells.

Musculotopic organization of the motor neurons supplying the mouse hindlimb muscles: a quantitative study using Fluoro-Gold retrograde tracing.

Tímea Bácskai et al.

Brain structure & function, 219(1), 303-321 (2013-01-05)

We have mapped the motor neurons (MNs) supplying the major hindlimb muscles of transgenic (C57/BL6J-ChAT-EGFP) and wild-type (C57/BL6J) mice. The fluorescent retrograde tracer Fluoro-Gold was injected into 19 hindlimb muscles. Consecutive transverse spinal cord sections were harvested, the MNs counted

Synaptic innervation to rat hippocampus by vasopressin-immuno-positive fibres from the hypothalamic supraoptic and paraventricular nuclei.

L Zhang et al.

Neuroscience, 228, 139-162 (2012-10-23)

The neuropeptide arginine vasopressin (AVP) exerts a modulatory role on hippocampal excitability through vasopressin V(1A) and V(1B) receptors. However, the origin and mode of termination of the AVP innervation of the hippocampus remain unknown. We have used light and electron

Neuroanatomical technique for studying long axonal projections in the central nervous system: combined axonal staining and pre-labeling in parasagittal gerbil brain slices.

N Kuwabara

Biotechnic & histochemistry : official publication of the Biological Stain Commission, 87(6), 413-422 (2012-06-21)

A method is described for studying the morphological features of extensive axonal projections within the central nervous system of the gerbil, Meriones anguiculatus. Potentially long descending axonal projections between the auditory thalamus and lower brainstem were used as a model.

Fluoro-Gold: composition, and mechanism of uptake.

M W Wessendorf

Brain research, 553(1), 135-148 (1991-07-05)

Determining the mechanism by which fluorescent retrograde neuronal tracers are taken up requires knowledge of their composition. It has been claimed that Fluoro-Gold, a retrogradely transported fluorescent neuronal tracer, is 2-hydroxy-4,4'-diamidinostilbene (hydroxystilbamidine), an amidine antibiotic. However, this appears questionable, since

Fluoro-Gold: a new fluorescent retrograde axonal tracer with numerous unique properties.

L C Schmued et al.

Brain research, 377(1), 147-154 (1986-07-02)

A new fluorescent dye, Fluoro-Gold, has been demonstrated to undergo retrograde axonal transport. Its properties include intense fluorescence, extensive filling of dendrites, high resistance to fading, no uptake by intact undamaged fibers of passage, no diffusion from labeled cells, consistent
