[Histonet] Help with frozen section staining

[Greg Dobbin]

Hi Pierre-André (neighbor),
I don't see the OCT being the most likely culprit, unless MAYBE if 
you were perfusing with it. The OCT should only be surrounding 
your tissue sections (not entering into them).  I would be more 
inclined to look at:
a) the fixative (try brand new batch, if the fixative is faulty, your 
sections will not tolerate the non-isotonic and perhaps acid or basic 
pH of your staining solutions). And then
b) the mounting medium (for clarity) and the coverslips for defects. 
(presumably you've ruled out the microscope as the problem?)
Good luck.
Greg
