Comments "A striking feature of clouds and tails associated with ActA-coated beads was the twisted appearance of the actin filaments. The persistence length for a filament of pure actin is approximately 10µm [primary source], and they break at a radius of curvature of less than 180 nm [ref 22]. However, many filaments in tails appeared curved or twisted over distances less than 1µm, with some showing curvature of less than 50 nm (e.g., Figure 4f,g)." See BNID 105505
