There are two (at least) "schools" on GFP One is direct visualization after
incorporation and the other involves immuno procedures using anti-GFP. When
you get responses to your question keep this in mind. I have sectioned many
frozen samples, covered slipped and viewed GFP direct. I have never had
successful visualization without using an antibody on processed tissue. When
you receive information regarding processed samples with direct
visualization PLEASE share the procedure on line as I know it is important
to many. anita
