Hello. I would like to find out which is best endothelial markers in mice with 10% formalin fixed paraffin blocks. If you have any input welcomed here. Thanks.

Are you looking for tumor associated endothelial markers? many of such markers are conserved both in mouse and human. Are you talking about the most common marker: PECAM-1 (CD31)? to see the mouse genome you can check the site: mouse genome informatic (MGI) data base at:

I hope I helped
