Co-localization of NF-κB and COX-2 in the cerebral cortex. Upper panel showing activated NF-κB (anti-p65 monoclonal antibody) in red; middle panel showing COX-2 in green; lower panel showing cellular architecture visualized with DAPI staining. Note double immunopositive cells (arrowheads) with cytoplasmic COX-2 and nuclear NF-κB staining (× 400).
