[Histonet] Histology and immuonhistochemistry of Drosophilaeyesections (OT)

[Jo Dee Fish]

Hi Pam,
I have worked with the little guys for a while now.  The best way is to
pre-embed in agar or histogel (although I have had a lot of bad luck with
the histogel getting "crispy" in our processor).  Put a small amount of agar
in a small mold, like the tissue tek plastic molds, then align the flies in
the orientation that you would like.  Then just process the entire block of
agar into paraffin and embed.  They cut beautifully.
Good luck,
Jo Dee

I have students here who have been doing cryo-sectioning of Drosophila. No
one, has yet tried it in paraffin. Since they are very tiny flies, we have a
contraption that allows us to orient the flies so that their heads are all
in a row and we just cut a whole bunch at once. It looks like a slide with a
long groove in it - just wide enough to fit their heads above it and the
bodies hang down below. It seems to work just fine.

Cheers, Peggy
