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 that unnecessary. Gayle M.

Cool down for 10 min. (This is our protocol.) 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. Good luck.

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. > Waiting to hear from you soon. > Thank you for your consideration > Best wishes > Hatem Salim <http://www.vanderbilthealth.com/main/> _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet
