|---|---|
| Allergen source: |
Major taxonomic group: Plantae Eudikotyledons Order: Fabales Species: Arachis hypogaea (Peanut, groundnut) NCBI Taxomony ID: 3818 |
| Biochemical name: | Seed biotinylated protein SBP65 |
| Molecular mass: | 57 kDa |
| Allergenicity: | Sera from 52 peanut-allergic patients were tested (positive open oral food challenge with peanut butter + positive peanut ImmunoCAP). Sera from 12 non-allergic donors served as negative controls. In an IgE-ELISA, 5 peanut-allergic patients' sera (10%) had IgE to rAra h 20.0101 produced in E. coli. |
