Re: Immunos on Mouse tissue

From:Barbara Wright


If you are using the DAKO CD31 antibody - it will not react with mouse
endothelium.  Pharmigen CD31 (MEC13.3) works well on FFPE with Vectastain Elite-
ABC followed by NEN TSA-kit.  And our Collagen IV is from a polyclonal from
Chemicon.  Both work well on FFPE mouse tissues.
