Hydroxystilbamidine

CAS 223769-64-0

Hydroxystilbamidine (also called Fluoro Gold) is used for staining DNA and RNA. It exhibits distinctively different fluorescence emission profiles when bound to DNA compared to RNA. This cationic dye is also frequently used as a retrograde neuronal tracer. Fluoro-Gold is a trademark of Fluorochrome, Inc.
