This same clone for Rat CD31 still sold by BD 
Biosciences/Pharmingen/Invitrogen, also Serotec, ABCAM and a  company called 
Research Diagnostics found in the IHC World protocol.   The latter protocol 
used Proteinase K digestion.

Colleen,

Many years ago I used Pharmingen's  anti-Rat CD31, clone TLD-3A12 (I think, you 
need to check it out if they still sell it).

This antibody is not recommend for formalin fixed paraffin tissues, but it will 
work.

Following steps are critical;
1) Do not use HIER, use enzymatic digestion (need optimization with Trypsin or 
Proteinase K @ 37c.  Lot to Lot variation from manufacture)
2) Overnight Incubation @ RT, not 4C (need warmer & long time)
3) Do not over dilute the 1st ab (ie. 1:10 - 1:25)
4) Try use a more sensitive detection system (Leica Refine DAB system) Good 
Luck!
