^aPeptides are identified by their three terminal amino acid residues using the one-letter code, followed by the total number of residues constituting the peptide.

^bED, extracellular domain; ID, intracellular domain.

^cUnconjugated peptides were used for immunisations except for ENI-17 and SLR-22 which were previously coupled to keyhole limpet haemocyanin (KLH) by 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide (EDC).
