Expression of myoglobin and cytoglobin in rat descending aorta and sheep femoral artery from each species. Myoglobin levels in rat arteries did not differ significantly from those of the sheep when normalized to either total protein (A) or myoglobin levels in homogenized rat or sheep myocardium (C). In contrast, rat arteries contained significantly greater levels of cytoglobin than sheep arteries when normalized to either total protein (B) or myocardium (D), since cytoglobin levels in sheep arteries were not detectable (ND). *P < 0.05, t-test; n = 3 for each tissue type.
