You can just add your strep-HRP or ABC step to a section (without primary
or secondary) and if you get signal it is surely from the biotin
endogenous to the tissue. It is a good control to run in any given
experiment.

Biotin is tricky as it often appears in very "specific" patterns and is
often misinterpreted as real staining.

I also agree HIER can dramatically increase biotin signal.
