Rotational motion of a dye tethered to actin studied by frequency-domain fluorescence anisotropy

The rotational motion of a fluorescent probe tethered to a protein provides a wealth of insight into local properties of the solvent and the protein. To investigate the rotational motion of rhodamine 6G (R6G) tethered to actin, a novel instrument for frequency-domain fluorescence anisotropy measurements was devised. The wobbling motion of the R6G could be measured, which was exploited to work out the local hydrodynamic property of the solvent around the conjugation site and the steric hindrance that the R6G experienced. This study revealed a difference in the dynamic property between bulk solvent and the hydration layer of actin.
