Re: [Histonet] Basic Fuchsin vs. Pararosaniline

From:Geoff McAuliffe

Hi Mareike:

    It depends on how much pararosanaline is in your basic fuchsin. 
According to John Kiernan modern samples of BF are almost entirely 
pararosanaline or rosanaline. Older samples may also contain new fuchsin 
and/or magenta II. If the dye is certified by the Biological Stain 
Commission you could contact them and find out what is in your batch. If 
it is not certified all you can do it try it or buy a new supply. Again 
we see the advantage of using certified dyes.
