Allergen Details:

Allergen name: Per a 12
Lineage: Source: Animalia Arthropoda
Order: Blattodea
Species: Periplaneta americana (American cockroach)
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 μg/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
