Response of Equatorial X-Ray Reflections and Stiffness to Altered Sarcomere Length and Myofilament Lattice Spacing in Relaxed Skinned Cardiac Muscle

Low angle x-ray diffraction measurements of myofilament lattice spacing (D(1,0)) and equatorial reflection intensity ratio (I(1,1)/I(1,0)) were made in relaxed skinned cardiac trabeculae from rats. We tested the hypothesis that the degree of weak cross-bridge (Xbr) binding, which has been shown to b...
