[Histonet] HPS Stain

[Gagnon, Eric]

Hi Sheila,
 
HPS (Hematoxylin-Phloxine-Saffron) is the routine stain we use.  There are a few institutions in Canada that also still use this stain; around Ottawa and a few other places in Ontario and Quebec.  Perhaps one of these institutions sent slides to your pathologist for referral/consult?
 
It is quite a nice trichrome stain, but somewhat more complex and expensive, uses more staining dishes, and it's sometimes tricky to get a proper phloxine/saffron balance.  Due to the use of H&E being more widespread, our pathology residents usually ask for H&E slides for their files when preparing for exams.
