Hi Tim,

Pharmingen's ICAM-1(CD54) (cat 22491D) works  well in rat paraffin
embedded tissue.  I use 2.5µg/ml of primary diluted in  Dako® antibody
diluent overnight at 4oC with citrate microwave pretreatment.  I use
biotinolated polyclonal anti mouse secondary (adsorbed to rat) and LSAB
(Dako®) with DAB.  (The catalog has the protocol in the back)  Adjust
for your particular  needs.  They have many antibodies made specifically
for use on rat and mouse tissues.
