Fluoro-Gold^TM is the most widely used and effective neuronal retrograde tracer in the world. Our Antibody to Fluoro-Gold is a sensitive antibody that will substantially enhance the visualization of Fluoro-Gold. 
Fluorogold, trade name Fluoro-Gold, is also known as hydroxystilbamidine.

VTA (40X) after Fluoro-Gold
injection in the accumbens.  Antibody is at 1/100,000.

Fluoro-Ruby provides a complimentary neuronal anterograde tracer to Fluoro-Gold and Antibody to Fluoro-Gold

Advantages of Fluoro-Gold:

• Intensely vibrant retrograde fluorescent tracer that is extremely sensitive and reliable
• Not taken up by undamaged fibers of passage
• Does not diffuse out of retrograde-labeled neurons
• Wide range of survival times from one day to over a month
• Stable fluorochrome that takes superlative color and black and white photographs
• Easy and safe
• Long shelf life
• Pure reliable source
• Can be pressure injected or iontophoresed
• Compatible with most other frequently used neuroanatomical techniques such as immunofluorescence, immunocytochemistry, autoradiography, horseradish peroxidase histochemistry, paraffin embedding and other retrograde fluorescent tracers

Advantages of Fluoro-Gold when enhanced by the Antibody:

• Substantially enhances visualization of Fluoro-Gold
• Allows much more precise anatomical mapping
• Shows extremely fine anatomical structure including dendrites, axons and terminals
• Results in permanent staining when used with Vectastain ABC kit

Fluoro-Gold and Antibody to Fluoro-Gold are easy, reliable and safe to use. Fluoro-Gold can be injected using several different methods including pressure, iontophoretic and other applications developed by a variety of researchers.
