Hi Gwin,
why donīt you use 4% Paraformaldehyde in HMSS (Hanks Modified Salt Solution,
which is a Hanks Buffer including magnesium and calcium) or PBS. I used this
even for electron microscopical immunostainings and it worked nicely giving
good ultrastructural preservation and I routinely use it for the paraffin
and cryostuff. By the way I worked on chicken retina and optic nerve....
 
Good luck and happy staining!
