Allergen Details
| Allergen name: | Pap s 2 |
|---|---|
| Allergen source: |
Major taxonomic group: Plantae basal Mesangiosperms Order: Ranunculales Species: Papaver somniferum (Opium poppy) NCBI Taxomony ID: 3469 |
| Biochemical name: | Legumin (11S globulin) seed storage protein |
| Molecular mass: | 52 kDa (non-reducing), 30 kDa + 20 kDa (reducing) |
| Allergenicity: | Of 36 tested poppy seed-sensitized patients (SPT, sIgE), 10 had allergic symptoms after oral food challenge. Of those, 10 allergic (100%) and 21 tolerant (81%) had IgE to natural Pap s 2 as shown by ELISA. As only the natural allergen was tested, which is a mixture of Pap s 2.0101 and Pap s 2.0201 (as shown by tandem MS), the contributions of the individual isoallergens to IgE binding was not determined. |
