Figure 2From: Multiscale mechanobiology: mechanics at the molecular, cellular, and tissue levelsHuman cardiac protein titin. a, A schematic of titin in the sarcomere. b, Structure of I27 domain of titin (Protein Data Bank, ID 1TIT). c, Typical force-extension data of titin I27. Curves are WLC model fits to each individual domain stretching event. The force-extension regions over which the WLC model was fit are in blue.Back to article page
