Allergen Details:
| Allergen name: | Hel a 16 |
|---|---|
| Allergen source: |
Major taxonomic group: Plantae Eudikotyledons Order: Asterales Species: Helianthus annuus (Sunflower) NCBI Taxomony ID: 4232 |
| Biochemical name: | 2S albumin seed storage protein, SESA20-2 |
| MW(SDS-PAGE): | 15 kDa |
| Allergenicity: | Sera from 30 subjects were tested. Among them, 17 patients were allergic to sunflower seeds (SFS), with SFS-specific IgE > 0.35 kU/L (ImmunoCAP). Control sera were from 13 patients tolerant to SFS but allergic to other foods. Seven of 17 (41%) SFS-allergic but none of the 13 SFS-tolerant food-allergic patients had IgE to Hel a 16, as measured by ELISA with the natural purified allergen. |
