Figure 3. Bmal1 and Cry expression in the human saphenous vein. Human saphenous vein was incubated at 37 °C, and sections were harvested at 3 h intervals from midnight (24:00) to 21:00 (9 PM) for a 21-h time span. At indicated times, saphenous veins were flash frozen and subsequently protein lysates isolated for western blotting (top panel) that was densitometrically quantified (bottom panels)
