RE: [Histonet] argentaffin vs argyrophil

From:"Tony Henwood"

Why not.

This seems an ingenious way of detecting argyrophil cells only.
This would be an interesting project. Stain various endocrine containing
cells and other silver attracting substances (eg lipofuscin & melanin)
with the two techniques and compare the results. Also include several
argentaffinomas and argyrophilic tumours.

   When  performing  an  argyrophil  stain (Grimelius) one must also per
form  an  argentaffin  stain (Fontana-Masson) to rule out the positive
   argenta=ffin  staining in the Grimelius procedure.  Would it work if
   you  perfor=med a Grimelius on two slides, but left out the reducing
   substance for one =f the slides?

   Thank you,
