Diana McCaig in Chatham, Ontario asks >>Can someone provide me with a
supplier of tissue marking dyes for use on the grossing bench.<<

You're referring to inks used to mark the margins of resected tissue
so that the pathologist can find the surgical margins under the
microscope. They're particulate inks suspended in a viscous medium,
rather than soluble dyes.

There are several brands of these inks. In my personal experience the
Davison marking inks (see bradleyproducts.com) - order direct from
them or through some of the standard vendors - are better than the
competition. (I have no commercial connection with Bradley Products.)

Some pathologists like tattoo inks - available in great numbers of
colors and quite cheap - but the catalogs you have to buy them from
are a real gross-out.

Most important thing about using any marking ink is to cap the bottle
promptly when you're through using it. Do that and they'll last for
