Anne - maybe try 0.03% in methanol.  It works pretty well for me with post fixed frozen sections of human tonsil.

Does anybody know a good protocol for blocking the
endogenous peroxidase? 
I am performing immunoperoxidase staining on rat
spleen frozen sections and I have tried to block
endogenous peroxidase with H2O2, 1% and 0.3% in PBS, 
half hour before the first antibody but is seemed to
be a too high concentration, as the tissue was
destroyed. 
Thanks for help!
anne
