Hey Daryl --
I have had good results visualizing Cy5 with a 100W HBO lamp on a
standard epi-fluor. 'scope using Zeiss' "00" filterset (excitation:
BP 530-585, beamsplitter: FT 600, emission: LP615) which is a filterset
designed for visualizing Texas Red. However, you can't see cy5
fluorescence by eye. If you have a CCD camera you can use it to capture
the Cy5 image as long as the CCD has decent spectral response above
~650nm. Many CCD cameras have an IR cut off filter so that they will
match human vision. For the camera I use (Dage 72) it was a trivial
matter to remove the IR cut off filter.
Good Luck,
