Lisa,
Your best bet is to contact CAP directly with your question(s).  They
have an e-mail address that I have used several times.  They answer
promptly and precisely.
The address is:

Good Luck,

I have a question regarding negative controls for a manual
immunoperoxidase procedure.  Do you use a neg control for each antibody
used with each block? or one neg control per block regardless of how
many antibodies for that block.  The latter is what I was told, but the
first seems more likely on account of  each antibody may be treated
differently with some needing antigen retrieval--obviously the contol
should receive identical treatment.  What is the usual neg control
protocol?
Thank you.
