Notes:
We have applied a theory of dynamic light scattering from large anisotropic particles, developed by Aragón and Pecora [J. Chem. Phys. 66, 2506-2516 (1977)] to calculate the scattering expected from T-even phage models. The results indicate that the off-center rotation of the massive virus head with respect to the center of frictional resistance introduces significant rotational contributions to the light-scattering time autocorrelation function. The effect is particularly important when the fibers of the phage are extended. Reanalysis of previously published data [J. B. Welch III and V. A. Bloomfield, Biopolymers 17, 2001-2014 (1978)], taking into account rotational corrections, confirms the equality of molecular weights of the slow- and fast-sedimenting forms of T2L bacteriophage.
