Data (means ± standard deviations for 2 to 5 experiments) represent numbers of phage particles in the initial sample and in the supernatant (after bead removal). Results shown for magnetic beads were determined using BCCP-T4 phage, and results shown for cellulose beads were determined using CBM-T4 phage.
