[Histonet] antibodies against phosphorylated proteins

From:"Heike Grabsch"

I am working with formalin fixed paraffin embedded tissue and trying to
detect phosphorylated proteins by immunohistochemistry. The antibodies
are meant to be specific for the phosphorylated protein only. 
The one antibody I am trying to work up in particular is the
phospho-H2AX from Upstate. 
Is there anybody out there who has an idea whether and if then how
fixation may effect phosphorylation sides? Can they be lost or destroyed
due to fixation? So the staining could be false negative?
I hope somebody can comment on this
