From: IgE Reactivity to Common Cypress (C. Sempervirens) Pollen Extracts: Evidence for Novel Allergens
IgE reactivity to Cup.s . SDS-pollen extract. M represents the marker; Cs, C. sempervirens pollen extract; lanes 1-24, screening of 24 patient's sera by Western blotting for specific IgE antibodies to Cup.s. pollen extracts and Co, the negative control using the serum of a healthy individual. Strips were ordered by the intensity and frequency of allergen recognition. Differential sensitization patterns were classified in 3 groups: A, represents patients showing heterogeneous IgE reactivity to HMW; B, an intermediate pattern recognizing both HMW and 14 kDa allergens; and C, patient's sera showing a specific IgE reactivity to the protein at about 14 kDa.
