Hydropathy plot of the glycoprotein precursor (GP-C) of Guanarito virus strain INH-95551. The plot was generated by using the Hopp-Woods scale and a window size of 7 residues. Analysis of the GP-C amino acid sequence suggested that the signal peptide (SP), G1, and G2 extend from the initiating methionine through residue 58, from residue 59 through residue 245, and from residue 246 through residue 479, respectively. It was expected that neutralizing epitopes would be clustered in hydrophilic regions with peak size > 0.5.
