What are you using for HIER?  Citrate buffer?  What pH?  
I use a low pH citrate buffer at 95C for 20 minutes and get good results.

Subject: [Histonet] Cytokeratin AE1/AE3

Hi Histonetters,

I just came across a thread regarding issues with Cytokeratin AE1/AE3 from DAKO. I am having the same issues with our
New protocol using HIER on the Link-48 in which sentinel lymph nodes from breast cases are staining non-specifically "in-between the cells".
We never had this issue before on our old Autostainer plus, however, we were using only enzyme pre-treatment on it before staining.
I was wondering if anyone else has come across this, and if they have fixed it?

Thank you,

Brandy Burnett, HTL
