SIRIUS RED F3B

Highly water soluble red dye, but has poor solubility in ethanol. Also called Direct Red 80 and in the class of Tetrakisazo dyes.

Employed as a substitute for acid fuchsin in van Gieson type procedures. It is also used for the demonstration of amyloid by hydrogen bonding, in techniques similar to those using Congo red. Like that dye it retains the green birefringence, but is a little darker.
