Descrizione generale

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.

A few properties of Hydroxystilbamidine bis (methanesulfonate) are:

  • 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.

Applicazioni

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. It is used to study morphological features of extensive axonal projections within the CNS by labelling the cells.

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

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
