Zip,

As I recall the best autofluorescent blocker we found which worked well with the
FISH exps. we were doing using DIG_FITC was 0.4% evans blue.  Try it and let me
know how it worked.

Subject:  Baboon auto-fluorescence ...

Greetings,

          We have a problem with measuring E-GFP fluorescence in
     transfected baboon cells. These exhibit marked auto-fluorescence in
     the green (FITC) band when excited with 488nm. light, which obscures
     the GFP signal. Now, I vaguely remember hearing somewhere (?) that if
     one excites at an alternative wavelength (I have an argon, mixed gas &
     HeNe lasers available, lucky me!) then this auto-fluorescence can be
     reduced & the GFP measured still. Is this the case & if so, what might
     be the appropriate excitation (& emission?) wavelengths ... ???

     Suitably appreciative,

     "Zip".
