[Histonet] Re: India Ink for marking surgical margin borders

[Bob Richmond]

Barry Rittman observes: >>One group of dyes that I do not believe has ben
mentioned is the Procion group of dyes. These are chloro-s-triazone dyes
that are used extensively in textile dyeing and are resistant to all the
solvents of which I am aware and will survive processing through paraffin
wax.  Readily available at many art stores. They come in a wide variety of
colors. They interact with proteins. Their drawback is that many are
fluorescent (and were originally intended as markers for hard tissue growth
due to their solvent resistance).<<

But if they aren't in insoluble particles, then I won't be able to see them
under the microscope!
