Allergen Details
| Allergen name: | Eup s 1 |
|---|---|
| Allergen source: |
Major taxonomic group: Animalia Arthropoda Order: Euphausiacea Species: Euphausia superba (Antarctic krill) NCBI Taxomony ID: 6819 |
| Biochemical name: | Tropomyosin |
| Molecular mass: | 35 kDa |
| Allergenicity: | Sera from 18 shrimp-allergic patients were tested (symptoms + positive ImmunoCAP). Of those, 6 sera (33%) had IgE to a band corresponding to tropomyosin in a Western blot of krill extract. Five of the positive sera were tested with purified nEup s 1 on Western blot, all of which yielded a positive signal. Al 6 krill-positive patients reported allergic reactions after consuming krill, the other patients have not consumed krill. |
