Beschreibung

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.
