Sirius Red F3B is available as Direct Red 80 C.I. 35780.  I would suggest
trying Sigma-Aldrich or Polysciences.

Help histonetters,
	I have a scientist wanting me to do a stain called Sirius Red
(Llewellyn, 
1970)  I have found a procedure in Bancroft's book.  Whew!  Then I look in 
I don't know how many catalogs and find Sirius Red F3B NOWHERE.  I looked 
in my old book of biological dyes for a possible alternate name.  No 
Luck!  Does anyone know where I can get this stuff.  AND once I find it any 
clues.  I have been warned that the preparation of this dye is tricky and 
it can precipitate out on you quite easily.  Thanks in advance!
