Hydroxystilbamidine is a fluorescent neuronal retrograde tracer that labels the neuronal cell body as well as proximal dendrites. It is also a nucleic acid dye that can be used to label DNA and RNA in fixed or unfixed dead cells. It displays an excitation maximum of 360 nm and emission maxima of 450 and 600 nm when bound to DNA but only emits at 450 nm when bound to RNA.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
