^aRegions for each linear epitope identified defined as in peptide numbers in the microarray library.

^bRegions for each linear epitope identified defined as amino acid numbers according to HXB2 envelope sequence. The range covers from the first amino acid of the first peptide within the epitope region to the last amino acid of the last peptide within the epitope region.
