Thorsten,
could you comment on the importance of TDE mountant purity?
Your article (MICROSCOPY RESEARCH AND TECHNIQUE 70:1–9, 2007) used the 
Biochemica grade TDE (>99%, Sigma #88559, 250ML for $160.50). I have 
been using the Aldrich cat. #166782 (>99%, 500g $27.70) with good success 
for conofcal 3D imaging of pollen grains (autofluorescent, no staining needed). 
It performed really well for these samples,  but I am uncertain if this lower 
grade TDE would work for e.g., immunostained slides.

Also, if anyone is using TDE with an antifade compound, I would appreciate 
information what you used, what concentration, and any specific tips on 
mixing.  

Thank you!
