[Tony Henwood]

"either would fulfill the purpose of detecting non-specific positive staining" - NO

Not in the patients sample unless it is included (which for diagnostic uses is the most important).

I can certainly agree with that. Whether it’s the patient’s sample or the known positive control that are stained without primary, either would fulfill the purpose of detecting non-specific positive staining.

I agree with the majority. A  patient slide stained without primary antibody, and a patient section with primary antibody and  a known positive control tissue, on the same slide when possible, is sufficient. I do agree, however, that the use of a negative tissue control is important in your initial antibody optimization and validation.
