Dear Gary,

may I propose you an alternative way for harvesting your root samples? It is a technology called Microsampling, which starts from the intact, living object. I shall say that I speak in my own interest, because I am part of a young company that develops microsampling solutions. As I read regularly the Arabidopsis List, I came across your question.
If you would like, let's speak about it, and then look how to make possible a proof of principle. We are sitting in Jena, Germany - but in spite of this distance we could find a solution via co-operation to local researchers. What do you think of it?

Best regards

We want to do an experiment where we use localized GFP expression as a marker to allow us to identify regions of plant roots to harvest by laser microdissection. However, all of the fixation procedures we try that are compatible with laser microdissection bleach the GFP so it cannot be seen.

Does anyone know of a procedure where the tissue can be fixed for laser microdissection that would retain GFP fluorescence and also RNA integrity?

Thanks for your help.
