We're testing new probes and filters for our microscope and amongst the
things we wanted to check was signal loss btw different filters as well
as intensity distribution across the view field (this is separate from
the filters of course). I found Invitrogen's FluoSpheres as well as
Fluor-Ref fluorescent slides (Ted Pella being one vendor here:
<http://www.tedpella.com/histo_html/fluor.htm>).
The reference slides are obviously much more economical, but they don't
list their emission spectra, and since the filters we're testing have
fairly different OD spectra, we would like the references to be as
similar to our probes. What are people's experiences and
recommendations with these references or others you have used?
