Chers Tous,

J'ai trouvé dans Mycologia 71, 1979, un article de R.J. Bandoni: Safranin O as a rapid nuclear stain for fungi. (chez Cyberliber)

Ma demande : Avez-vous de l'expérience avec ce colorant nucléaire ?

Merci de vos réponses

René

Re : Demande
Hi René,
          I don't know if this is of any help. I have tried using o-safranin as a counterstain with toluidine blue. It didn't work but I use this mix for thin structure like paraphyses (in the attached photo from Propolis farinosa). It tends to overstain quickly.

I tried simple staining with o-safranin alone but I am not sure what I should see. I rarely use acetocarmine stains as I get mixed results with precipitates and unclean slides. I am attaching some tests on a Tarzetta - cupularis or gaillardiana (some spores are in the 26-27µm range). The stain was a 1% water solution added near the coverslip.
