[Histonet] cytokeratin

[Lombaert]

Dear Histonetters,

Has anyone tried to stain cytokeratins (7, 8.12, 14 and 18 from 
Sigma) on mouse/murine salivary gland tissues? I already tried 10 
mM sodium citrate pH 6.0 for 30 min in the microwave, 

as well as 0.1M TrisHCl pH 9.5,
no target retrieval at all,
proteinase K for 5 min (20 mg/ml)

but no results. I only could detect something with the enzym 
proteinase K, although my tissue was disrupted badly. 
My sections are paraffine imbedded and 4% formaldehyde fixed. 


Kind regards,
Isabelle
