[Histonet] Warthin Starry on Dako Artisan

[Sanders, Jeanine (CDC/OID/NCEZID)]

What protocol with uranyl nitrate do you use? Dako told us to use zinc formalin as a sensitizer but it doesn't seem to make much of a difference. Thanks!

 Happy Holidays Histonetters!

Has anyone out there successfully stained spirochetes with Dako's Artisan Warthin-Starry kit, without first pretreating the sections with uranyl nitrate?  With offline uranyl nitrate pretreatment, spirochetes stain brilliantly!  But everything else we've tried leaves them invisible . . .

Any guidance would be greatly appreciated.

Thanks,
