^aMicroarray summary statistics were calculated using GeneSpring (version 7.3.1) and Microsoft Office Excel 2003 software. Raw fluorescence intensities from the average of triplicate arrays were used. BALB/c mice were immunized with the FT04-peptide conjugates.

^bCorrelation is the Spearman correlation, which considers only the relative rank of array features.

^cImmunogen rank is the feature corresponding to the peptide immunogen, with 1 being the feature with the highest raw fluorescence intensity. The top-ranked peptide in this experiment is highly reactive to the detection reagents.
