Product Description

Hydroxystilbamidine (also called Fluoro-Gold™) has been used extensively as a retrograde tracer for neurons and also a histochemical stain. Fluoro-Gold™ can undergo retrograde axonal transport, it shows extensive filling of dendrites, and has a high resistance to fading.

This product is provided as a ready-made 4% solution in deionized H2O. If desired, the solution can be diluted to a lower concentration. For most applications, the typically dye concentration is 2% to 4%. Note: The dye solution is produced using type I ultrapure water, but it is not prepared or packaged aseptically, and should be sterile-filtered for aseptic applications. We offer Mini-Syringe Filters, which are convenient for 0.2 um filtration of small volumes of aqueous solutions.

We also sell hydroxystilbamidine in solid form (10 mg, cat#80014).
