Figure 3From: A highly conserved WDYPKCDRA epitope in the RNA directed RNA polymerase of human coronaviruses can be used as epitope-based universal vaccine designAntigenicity of the conserved peptide. The conserved peptide was found to be highly antigenic in the IEDB analysis [27]. Most of the residues were found above the threshold 1.00. Residues in the yellow region are antigenic and in the green region are below the threshold (red line).Back to article page
