Allergen Details:
| Allergen name: | Per a 11 |
|---|---|
| Allergen source: |
Major taxonomic group: Animalia Arthropoda Order: Blattodea Species: Periplaneta americana (American cockroach) NCBI Taxomony ID: 6978 |
| Biochemical name: | alpha-amylase |
| MW(SDS-PAGE): | 55 kDa |
| Allergenicity: | Sera from 39 of 40 (83%) patients reacted to Per a 11 on immunoblots. ELISA inhibition of serum IgE reactivity to the cockroach midgut extract (CME) using purified Per a 11 was significant (60%). Twelve of 15 (80%) cockroach-allergic patients had positive SPT reactions to Per a 11. In comparison with healthy control, Per a 11 at 1.0 g/ml induced approximately up to 5.8-fold increase in the number of CD63 and CCR3 double-positive cells following incubating it with PBMC from patients with cockroach allergy |
