WebFeb 13, 2007 · In particular, the 2-μM actin traces typically exhibited large and irregular fluctuations in the bead position at the final force plateau ( Fig. 4 b ). We performed 11 independent experiments with actin monomer concentrations of 4 and 2 μM, with profilin kept at a constant molar ratio of 5:1 relative to actin. WebFeb 22, 2024 · By recording over a million cycles of force-on/force-off, the researchers collected a large data set of bead movements with roughly the same starting and finishing positions ( x 1 and x 2) or velocities. The statistics of forward and reverse processes agreed with the predictions from DFT, as well as other relations. country inn suites lackland
