Figure 2 Western blotting of bradykinin type-2 receptors (BK-2Rs) in human hearts. (A) Representative Western blot showing the expression of BK-2R proteins in normal and failing human hearts. Equal amounts of protein (30 µg/lane) were loaded onto the gel. (B) The relative amounts of BK-2Rs were quantitated in the different patient groups by measuring the optical densities (OD) in the Western blots. *p = 0.04. **p = 0.002. CHD = coronary heart disease; IDC = idiopathic dilated cardiomyopathy.
