1 Recombinant birch pollen allergens (rBet v 1 and rBet v 2) contain most of the IgE epitopes present in birch, alder, hornbeam, hazel, and oak pollen: A quantitative IgE inhibition study with sera from different populations  Verena Niederberger, MDa, Gabrielle Pauli, MDb, Hans Grönlundc, Renate Fröschla, Helmut Rumpold, MDa, Dietrich Kraft, MDd, Rudolf Valenta, MDd, Susanne Spitzauer, MDa  Journal of Allergy and Clinical Immunology  Volume 102, Issue 4, Pages (October 1998) DOI: /S (98) Copyright © 1998 Mosby, Inc.

2 Fig. 1 Inhibition of IgE binding to nitrocellulose-blotted natural tree pollen extracts (A, Betula verrucosa/birch; B, Alnus glutinosa/alder; and C, Carpinus betulus/hornbeam) with a combination of rBet v 1 and rBet v 2. Nitrocellulose-blotted tree pollen extracts (D, Corylus avellana/hazel; and E, Quercus alba/oak) were probed with sera from 11 representative patients allergic to tree pollen (panels 2 to 12) and, for control purposes, with serum from a nonallergic individual (panel 1). Sera were preabsorbed with a mixture of rBet v 1 and rBet v 2 (lanes +) or, for control purposes, with BSA (lanes-). Molecular weights are displayed at left. Black arrows indicate position of Bet v 1 and Bet v 1-homologous allergens, and grey arrow indicate those of Bet v 2 and Bet v 2-homologous allergens.
