Details about Masson Trichrome Stain !
 
Biebrich Scarlet:
Biebrich scarlet 2.7 gm
Acid fuchsin 0.3 gm
Distilled water 300.0 ml
Glacial acetic acid 3.0 ml
 
I am not sure what the Biebrich Scarlet here is ? Acid Red 66 or acid Red 73 ?
 
Acid Red 73 http://www.sigmaaldrich.com/catalog/ProductDetail.do?lang=en&N4=49823|FLUKA&N5=SEARCH_CONCAT_PNO|BRAND_KEY&F=SPEC
 
Acid Red 66 http://www.sigmaaldrich.com/catalog/ProductDetail.do?lang=en&N4=B6008|SIGMA&N5=SEARCH_CONCAT_PNO|BRAND_KEY&F=SPEC
 
What is the main difference between these two? 
May I choose 66, 73 or anyone?
 
Thanks !
