Barb, Eric, all-
We also use a diamond pen/pencil-and they do contain an industrial grade
diamond, so they are quite reasonably priced; I looked one up on the VWR
website (just as a reference, not necessarily an endorsement! :o) and they
run about $20-30 each. They last a very long time, too-We¹ve had ours for
We use them for our direct IFs, FISH, anything dark field.

Hi all -
The pathologist that reads our direct IF slides likes to have the sections
of tissue circled on the slide so that they are easier to find. We
currently use black marker on the back of the slide, but find that many
times it smears and are looking for a better solution.
What kind of slides do others use, and if you circle your sections what
marker/pen/etcher do you use?
Any thoughts are greatly appreciated!
