Objective: IgE reactivity has been investigated in the patients who sensitized to Betula pendula Roth (syn= B. verrucosa) pollen that distributed widely in nature habitat and also in park and gardens in Turkey.
Materials and Methods: Protein profile of pollen was studied by SDS-PAGE and transferred to polyvinylidenfluorid (PVDF) membrane. IgE reactivity profiles have been assessed via 10 patients who sensitized to pollen.
Results: It has been found that 86% (n= 6) show a positive reaction to 17 kDa (Bet v 1), 29% (n= 2) of sensitized seven patients has show a positive reaction to 15 kDa (Bet v 2). Only one patient show a reaction to protein which has 14.5 kDa molecular weight.
Conclusion: Our preliminary results have shown that the most common IgE reactivitiy was against Bet v 1 in Betula pollen allergy in our country similar to many European countries.
