Effects of buffers and storage conditions (time and temperatures) on the infectivity of the spiked phages (Phi X174, c2, and T4) during 100-day storage. The percentages of phages recovered (y-axis, log scale) were determined by plaque assay at each different time point (x-axis). The error bars indicate the standard deviation with 3 replicates. No dots or lines indicate plaques were not detected. The left panels (A, C, E) represent the temperatures 25 °C (dotted lines) and 4 °C (solid lines) and the right panels (B, D, F) represent the temperatures 20 °C (dotted lines) and 80 °C (solid lines)
