Good advice since actively boiling buffer puts mechanical stresses on
section, with bone more easily loosened by this action. It may help to
preheat the buffer to 95C before slide/section immersion into retrieval
buffer. A friend who is an IHC expert always did this, plus she used plastic
coplin jars (safer!).
Also, we dry all our decalcified, paraffin embedded bone slides FLAT, at 37C
to 40C for overnight, with longer better - be sure slides are well drained
before laying them flat. You can go to a 56C paraffin oven for a short time
(just enough to melt paraffin) after overnight if you desire, but you find

I would recommend the following:
Citrate for 35 min at 95 deg. Cool down for 10 min. (This is our
Be sure you are using charged slides and I would let them air dry for at
least 1 hour before heating and deparaffinizing. That might help, too.
Unfortunately, I don't think there is an effective method of retrieival that
will completely eliminate the possibilty of floating tissue.

I am Research assistant at Physiology department of Michigan state
university. I am using the (ß-Catenin Antibody (Carboxy-terminal Antigen)
#9587 for IHC on mice femur sections. I have used this antigen unmasking
method: For Citrate: Bring slides to a boil in 10 mM sodium citrate buffer
pH 6.0 then maintain at a sub-boiling temperature for 10 minutes. Cool
slides on bench top for 30 minutes.
The problem is that bone detachment always occurs so I wonder if there is a
method of retrieval that prevents bone detachment.
