[Histonet] RE: Fluorescence staining

From:"C.M. van der Loos"

   Dear Eva,

   To my knowledge most of the traditional fluorochromes like FITC,
   rhodamine, doesn't stand dehydration at all. So in your case it fully
   depends on what type of fluorochrome you end up with after the TSA

   If you end up with FITC, the use of VectaShield
   ([1]www.vectorlabs.com) for mounting is highly recommended for
   the prevention of photobleaching.

   [Histonet] Fluorescence staining

   We  are looking into trying some Fluorescence staining. We want to try
   a  TSA  Fluorescence  System  from  PerkinElmer. The IHC protocol does
   however leave me with some questions.
   We  always  dehydrate our samples after staining. The protocol however
   doesn't mention this. It only says that the samples can be
   counterstained and mounted after incubation with the Fluorophore
   Tyramide. Should we dehydrate and is there a particular mounting media
   we  should  use to prolong the time that fluorescence can be detected?
   Any help would be greatly appreciated.
   Thanks in advance for all your help,
