toluidine blue/Na borate
I have a question or two. What is the difference between 1%toluidine blue used
alone and 1% toluidine blue added to 1% Na borate. I know that toluidine blue
is used on paraffin sections for mast cells. I looked in histonet archives,
but did not find an answer to my question. Does anyone know why na borate is
added? I know that 1% toluidine blue alone is dark blue with light blue; add
na borate and you get purple and blue.
Any help appreciated!!
