Kathy,

Yes, we have frozen formalin fixed tissues in several instances in the
past.  We would rinse the formalin (or 70% alcohol if that is what the
tissue is stored in) and place the tissue in an embedding mold filled
with OCT and freeze onto a chuck.  This worked well for a number of
tissues and was helpful in doing a quick special stain or
immunohistochemistry.

 Is it possible to formalin fix a tissue and then put it in OCT and
freeze it to cut frozen sections?
