A brain tissue section (FFPE) from a patient who succumbed to Alzheimer’s was imaged with a 25-marker CODEX® panel. The image shows how the patient’s brain was littered with protein plaques (amyloid, blue) and how the glial cells (GFAP, red) circle around the plaques, trying to contain the damage. The CODEX® System enables researchers to visualize dozens of biomarkers in a single tissue section and study disease biology with greater depth and resolution.
