Method (For this research, table has values from other researches) 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 The EI (flexural rigidity) values and persistence lengths reported in the literature for actin filaments do largely agree on values of EI˜7×10^-26N×m^2 and Lp˜17µm with some outliers at up to about four times lower values
