Dear Histonetters,

This is my first time using this histosearch email.  I just discovered it 
a few weeks ago.  My lab is wanting to start looking for B7-H1 (PD-L1) in 
human tumor tissues that were fixed in paraffin.  I have this working in 
frozen tissue ( HRP detection kit from BD) but haven't been able to get it 
to work in paraffin.  And I cant find a commercially available antibody 
that says it works in paraffin.  Does anyone know of a commercially 
available B7-H1 (PD-L1) antibody for human paraffin tissues?

Thank you in advance,

Mayra
