We have also been experiencing non-specific staining and do not use CC1
but retrieve offline. The problem appears to be with specific lot # of
detection kits. Ventana is aware of this problem and should be working
with you to resolve it.

Particularly those using Ventana IHC Stainers.
We have a Ventana Benchmark and recently (from the middle of May) we
have a problem with antibodies which have had a pre-treatment in CC1.
1 After CC1, whether mild or standard we are getting non-specific
type staining. However, when you look at the slides they look specific
in their staining although for the wrong antibody. The negative
controls are displaying this phenomenon as well.
2. The staining can be blocked with the Avidin-Biotin block, but this
not always remove the staining completely.
We are using Batch #'s 48091 & 48127 of CC1.
Any advice would be greatly appreciated.
