mounting media containing phenylenediamine may cause some trouble for
long-term storage. I use for Cy3 where these problems did not appear
Vectashield as mounting solution.  In the specimen stained with Cy2
and "treated" with Vectashield the fading was also too much ( but it
contains phenylenediamine). I think I will try Mowiol or Dabco as
mounting media.

Thanks for your and everybodies advice
