Method Researchers report a new approach to obtain the flexural rigidity by means of well-controlled active experiments using optical tweezers to bend the filaments locally, as schematically depicted in Figure 1. In this way force-extension curves were measured for taxol-stabilized microtubules and rhodamine-phalloidin labeled actin filaments.
Comments Value in range is standard error of the mean.
