[Histonet] Phosphotungstic acid

[Cecilia A.]

Hello Histonetters,

I was wondering if anyone might be able to give some input regarding the
use of Phosphotungstic acid in which we want to soak formalin fixed soft
tissue for a few hours before it gets processed. Will subjecting it to PTA
before processing affect its viability for further histology work (ie, H&E
staining and IHC)?

Thank you very much!
