Inhibitory specificity of peptide H. Peptide H was incubated with the TGEV, PEDV and PrV at 37 °C for 1 h followed by infection of susceptible cells and plaque assays. The concentrations and reductions in virus titers are indicated. Peptide concentrations 1, 2, 3, 4, and 5 are 250 μg/ml, 125 μg/ml, 62.5 μg/ml, 31.25 μg/ml, and 15.625 μg/ml, respectively. Bars show the standard deviation from three independent assays.
