[Histonet] Trying to get consensus - Frozen section immediate post fixation or air dry

[Gayle Callis]

John,

How you treat a frozen section is going to depend on what you are planning 
to do with the frozen section.  If you can be more specific that will help.

Do you want to immunohistochemical staining on a snap frozen tissue?

Do you want to fix and then store these frozen sections for 
immunohistochemistry?

Do you want to store an unfixed frozen section for future 
immunohistochemical staining?

  Do you want to do a rapid H&E for diagnostic purposes?

We do any one of the above depending on a particular staining procedure 
needed.
