Force–distance curves for A-band regions of Dextran-treated single myofibrils. a Rigor and b relaxed myofibrils in a 0 %, b 2 %, and c 8 % Dextran. The origin of the abscissa is the position of the cantilever at the surface of the cover slip. Arrows the tip of cantilever just made contact with the surface of the myofibrils. Asterisk force versus distance curves for the cover slip
