Dear Gayle,

Thank you for your reply about the MDM2 staining.
I used citrate buffer in the Decloaker (a pressure cooker) for 5 min and
incubated with primary antibody overnight at room temperature and used a
polymer detection system (Ultravision) from LabVision for 30 min. I also
tried EDTA buffer and protease without much success.

With BondMax autostainer, I used pretreatment for 20 or 30 mininutes with
two different buffers (ER1-citrate based and ER2-high pH buffer) and ER2
gave much sharper nuclear staining. The primary incubation time was 30
minutes. The detection kit I used was Bond Polymer Refine Detection kit.

Thank you.

If you tell us HOW you do your protocol, then people can help with your 
background staining - which can come from many sources?
