Kim,

It is commonly used as a counterstain for fluorescent antibody staining so
that rather than seeing just a black background, the tissue stains with the
Evan's blue. Under the fluorescent microscope the tissue will appear red.

Does anyone know what this is used for?  Is it a vital dye?
I can't find any information on this in any of my reference
books.
