Allergen Details
| Allergen name: | Per a 12 |
|---|---|
| Allergen source: |
Major taxonomic group: Animalia Arthropoda Order: Blattodea Species: Periplaneta americana (American cockroach) NCBI Taxomony ID: 6978 |
| Biochemical name: | Chitinase |
| MW(SDS-PAGE): | 45 kDa |
| Allergenicity: | Sera from 30 of 40 (63.8%) patients reacted to Per a 12 on immunoblots. ELISA inhibition of serum IgE reactivity to the cockroach midgut extract (CME) using purified Per a 12 was significant (40%). Nine of 15 (60%) cockroach-allergic patients had positive SPT reactions to Per a 12. In comparison with healthy control, Per a 12 at 1.0 g/ml induced approximately up to 5-fold increase in the number of CD63 and CCR3 double-positive cells following incubating it with PBMC from patients with cockroach allergy |
