Aorta: Oil Red O vs. Biomolex 700

From left to right, the animal aorta was stained with Oil Red O to identify the lipid deposits followed by the processed Oil Red O image to define plaque and non-plaque areas. Finally, with a 5x5-pixel mean filter applied, digital autoradiography images of the same aorta, separated into contributions from the different radiotracers. Each image is individually scaled from zero (white) to max (black) uptake and does not reflect differences in total uptake between tracers. © 2013, Anders Örbom.
