Allergen Details:

Allergen name: Hel a 15
Allergen source: Major taxonomic group: Plantae Eudikotyledons
Order: Asterales
Species: Helianthus annuus (Sunflower)
NCBI Taxomony ID: 4232
Biochemical name:2S albumin seed storage protein, SESA2-1
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. Eleven of 17 (65%) SFS-allergic but none of the 13 SFS-tolerant food-allergic patients had IgE to Hel a 15, as measured by ELISA with the natural purified allergen.
