Which activity is a laboratory responsibility in antibody validation requirements?

• A. Confirm product performance.
• B. Advertising to customers.
• C. Manufacturing.
• D. Internal audits of unrelated products.

Answer: (A)

In antibody validation, the lab must prove that the antibody performs as expected within its actual assay workflow. This means confirming product performance in the lab’s own conditions—demonstrating specific, sensitive, and reproducible staining on the relevant tissues with the lab’s protocol, controls, and equipment. Marketing activities like advertising, manufacturing processes, or auditing unrelated products do not address how the antibody behaves in the lab’s hands, so they’re not part of the validation responsibility.
