RE: long term storage of cytology preps

From:"Sebree Linda A." <>

Hi Deb,

We have additional cytospins or ThinPreps made from cases that would make
good control material when possible.  The cytology lab fixes these for us in
acetone for 10" and we store them at -20 degrees C.  We have not done a
formal study of possible loss of antigenicity.
