Thank you everyone for replying, much appreciated.

Having also talked to people in my dept, I have a rudimentary protocol
ready. Of course, I will have to tweak it to see what works. I will be using
anti PGP9.5 antibody for neuronal immunology.

I am still not sure how to section the wing. In most likelihood, I will be
using freezing sliding microtome. The "swiss roll" method sound good and I
will definitely try it. I am thinking that since the wing membrane is thin
(~30 um), I will also try to use the whole mount of small pieces.

Any other thoughts and advice would be appreciated.

Thank you,
