I have done immunostaining on free floating scetions of Rat brain.
Tissue fixed, by perfusion in 4% Para, then cryo protected with 30%
sucrose. Sections cut at 50um, then placed into 500ul PBS in a 24-well
plate. (I had approx 4-5 sections per well)

500ul is plenty in a well, especially if you are using a fair dilution
of antibody cos then you dont use too much.

I did all my staining in the plate, and the sections looked wonderful!

Hope this is of some help,
