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.
噬菌体P22尾部与头部的结合通常是不可逆的,但在吸附到宿主细胞后,超声处理能完整释放出许多尾部。这种释放取决于超声处理的功率,但与2至32秒的超声处理时长无关。这一现象已被用于表明能够结合到一个细胞上的P22颗粒数量上限不低于700个。
