Allergen Details

Allergen name: Sui p 2
Allergen source: Major taxonomic group: Animalia Arthropoda
Order: Sarcoptiformes
Species: Suidasia pontifica (Scaly mite)
NCBI Taxomony ID: 2058792
Biochemical name:NPC2 family; MD-2-related lipid recognition (ML) domain containing protein
Molecular mass:14 kDa
Allergenicity:100 allergic patients with mite allergy were diagnosed with standardized questionnaires (allergic rhinitis, asthma or atopic dermatitis combined with typical mite-associated symptom exacerbation). Of those, 82 has specific IgE to Suidasia pontifica extract (by ELISA). Of the sera from Sui p sensitized patients, 40 (49%) had IgE to recombinant Sui p 2.0101, while only 1 of 100 non-allergic donors' sera has Sui p 2-specific IgE. In an inhibition ELISA, IgE binding to Sui p extract was inhibited by rSui p 2 by > 50% with 4 of 6 Sui p 2-positive sera.
