Antibody for chicken endothelial markers

[alberto.rissone at ircc.it]

I'm working with the chicken embryos. 
Does anyone know a good commercial antibody specific for the chicken endothelium (like CD31, FVIII, Endoglin, or any other
possible marker) and suitable in IHC (formalin fixed, paraffin embedded tissue sections)? 
Please help me! 
Thanks. 

Alberto.
