[Histonet] Re: Details about Masson Trichrome Stain !

[Bob Richmond]

Wang Lian MD, Medical School of Nanjing University in China, asks
whether Biebrich Scarlet is Acid Red 66 or Acid Red 73.

According to R.D. Lillie (both Histologic Technic 3rd ed. and Conn's
Biological Stains 9th ed) states that the 2nd edition of the Colour
Index (a rare book I have never seen a copy of) refers to Biebrich
scarlet as Acid Red 66.
