Binding analysis of the selected phages to SARS-CoV S1 protein in ELISA. Ten selected phages, phage 1 to phage 10, were incubated with the SARS-CoV S1 protein in ELISA plates to determine the specific binding activities for the protein as described in Study design. The OD₄₉₂ value of tested individual phage and the control is shown on they axis; the individual phage and the control phage complex from the phage library are shown on the x axis. Three independent experiments were repeated for each individual.
