*MW (molecular weight in g/mol).

**pI (isoelectric point).

#Instability index (value of instability index smaller than 40 is predicted as stable, a value above 40 predicts that the peptide may be unstable).

##Aliphatic index (larger values represent increase of thermostability of the peptide).

^GRAVY (positive GRAVY values indicate hydrophobic nature of peptide and negative values indicate hydrophilic nature).

^^Antigenicity index (values represent peptide antigenicity).
