All,

I have a Dermatopathologist that is saying my Factor XIIIa antibody is not
working because it stains patient tissue that is also positive for CD34.
Does anyone know if these two antibodies are necessarily exclusive from each
other and will never stain positive on the same tissue?  I would like to get
the histonet's perspective before I pull my Factor XIIIa from my list.  BTW,
both antibodies stain their respective controls just as they should.

Thanx In Advance,
