  DiI is soluble in alcohol and other organic solvents. It should
  be OK for gelatin embedding if the tissue needs more support,
  but you will then have to cut frozen sections. Possibly one of
  the water-soluble (PEG) waxes would be OK. They are troublesome
  to cut for people who do not work with PEG all the time.
