I tried Zinc fixative I made myself. Does not work at all? And, the tissue quality is very bad. Any comments?

Nor how you are doing the actual staining method? More information would help please. If you are trying to stain for murine CD markers or some other cellular antigens, there are not many that work after FFPE. If you need to know this information, go to SEROTEC and look at murine CD or other cellular markers, and see if the antibody will work with FFPE paraffin applications. BD Bioscience also has applications that work, tested, reported, IHC or frozen sections and found in their Technical Data Sheets for any given antibody. There are some other fixatives to try for CD and other cellular markers - SEROTEC often refers to PLP (paraformaldehyde-lysine-periodate with recipe found on web through IHCWorld or Immunoportal, Google the keywords) while BD Bioscience refers to Becksteads Formalin free Zn TRIS buffer fixative. If you need the recipe for that, I will be happy to send. Otherwise BD Bioscience would be happy to sell that to you but it is cheaper and easy to make up in the lab. Gayle M.

Can this really be the problem in light of antigen retrieval methods?
