One of our Pathologists was at a meeting and one of lecturers
{Italian} said ".....get the results of keratin immunostains on fresh
frozen tissue 40 minutes after it is cut."   
  I was asked to look into this to see if anyone does these rapid
immunostains and if so is it a "homebrew" or is it a commerical kit. I
know that there are immunostains that can be done in a few hours, but 40
minutes from cutting to microscope is a bite short???
