After I deparaffinize running the slides down to water I use Target
Retrieval Solution from Dako Cat# S1699.  This is a 10X concentration that
you are to use at a 1:10 dilution.  They also have it in a Ready to Use 
solution.  I set up the steamer at least 30 minutes before hand, put the
solution in a plastic coplin jar and place the coplin jar in the
center of the steamer, if I have one coplin jar, or evenly spaced out in
the steamer if there are more than one coplin jars.  I set the steamers
timer for 30 minute pre-heating.  After pre-heating I place the slides in
the hot solution and incubate for 30 minutes.  Then I (carefully) pull the
coplin jar(s) out of the steamer and cool down for 20 minutes.  Then place
slides into buffer and continue with protocol.
