Abstract
An N-terminal peptide of the major allergen of birch (Bet v I 23-38) was selected for studying the activity of this segment on the basis of optimal hydrophilicity as it was tentatively suggested to be a surface exposed epitope. In addition two control peptides in the region 1–38 were similarly used for comparative assignment of the allergenicity. Peptide analoges from the amino acid terminal region, amino acid residues No. 23–38 of Bet v I, were synthesized by semiautomatic solid-phase peptide synthesis. In vitro and in vivo biological activity studies were performed on these analogous peptides. The IgE-binding capacity of the synthetic peptide 23–38 was examined using the following tests: specific IgE inhibition, skin prick test, nasal provocation and Prausnitz-Küstner inhibition. The results of these investigations suggested that the region 23–38 from the birch and hazel major allergen encompassed a single haptenic epitope.
