摘要：

The diameter of the actin filament is influenced by osmotic stress, being 9.0 nm at 1 × 105 dynes/cm2 and 6.8 nm at 9.00 × 106 dynes/cm2. At 1.81 × 105 dynes/cm2, the protein osmotic pressure in frog muscle, the diameter is 7.95 nm. The diameter of the tropomyosin-decorated actin filament is also influenced by osmotic stress even though, at the low pressures (up to 2 × 105 dynes/cm2), the decorated filament is significantly more resistant to compression than the undecorated actin filament. © 1994 Acdamic Press.
