The incidence of positive skin test responses among alopic subjects with suspected respiratory allergy was investigated with commercial and autochthonous pollen extracts of various cultivars of Olea europaea . Pollen was collected from olive trees of well‐defined cultivars, extracted, and separated by SDS‐PAGE. Immunoblots were used to identify the various IgE‐binding proteins of the pollen extracts of the various cultivars. The results revealed six predominant IgE‐binding bands, some of which appear in all the cultivars examined. The 18–20‐Da band (Ole e 1) appeared in only eight of the cultivars, but not in the nine others. The presence of specific IgE‐binding bands in the various pollen extracts and their correlation with the incidence of positive skin tests are discussed.
