No problems - but you would have rat on rat problems if you were using a 
rat host primary i.e. Rat antiRat primary.

You can use a donkey or goat antiMouse secondary adsorbed to rat tissues, 
preferably an F(ab')2 frag of IgG - Jackson has excellent secondaries for 
this.  We used a goat antiMouse isotype i.e IgG1, 2, etc -biotin conjugate 
from Southern Biotechnology.  The latter was very clean and I strongly 
recommend these.

Just do normal serum blocking carefully - you could even add 1% rat serum 
to the normal serum block with either goat or donkey serum but I don't 
think that will be needed.
