Sonic fragility of the head-tail bond of bacteriophage P22.
The binding of tail parts to the head of phage P22 is normally irreversible, but after adsorption to host cells sonication releases many of the tail parts intact. This release is dependent on the power of sonication, but is independent of the length of sonication from 2 to 32 s. This phenomenon has been used to show that the upper limit of the number of P22 particles that can bind to a cell is no lower than 700.
