Well, firstly I'll say that I havent had a great deal of experience with
them, but... Recently we changed to an Alexa fluorochrome from FITC and
it was MUCH better - brighter and a lot more photostable. The signal
from our samples were just visible with FITC, and after repeating the
procedure with Alexa they were very clear and perfectly visible.
