Nicole, You might look into using a more gentle heat source, such as a vegetable steamer or water bath. There are also pressure cookers for IHC which may also be easier on your tissue that the autoclave, although I have had problems with them as well and stick to steamer or waterbath myself. Patsy

I usually do it in an autoclave for 15min at 121C for FFPE human brain tissue (in Citrate or Tris Buffer), but by the end my tissue looks pretty bad and parts have even fallen off. The tissue is fixed on SuperFrost Plus Slides. Any suggestions would be really helpful. Thanks! N.
