I  am having huge problems with unperfused rat eyes. Shortly after the
   eyes are enucleated  I place them in oct and snap freeze the tissue in
   2-methylbutane placed in liquid nitrogen. After sectioning the tissue,
   I fix it for 10 min. in 4% paraformaldyhde and follow the HNE antibody
   protocol.  The results are that the photoreceptors are almost gone and
   the rest of the tissue looks completely degenerated. What went wrong?
