Fel d 4 is a lipocalin allergen produced by the cat, which binds IgE at relatively high frequency in cat-sensitive individuals. The allergen provides not only a means for investigating differences in the immune response to lipocalin allergens from that found for other mammalian species but also an important reagent for the diagnosis of cat […]

Abscisic acid (ABA), also known as abscisin II and dormin, is a plant hormone. ABA functions in many plant developmental processes, including bud dormancy. It is degraded by the enzyme (+)-abscisic acid 8′-hydroxylase into phaseic acid.

Of 30 patients allergic to London plane tree pollen, 83% showed serum IgE binding to 43 kD protein on immunoblot of P. acerifolia extract.

Major apple (Malus domestica) allergen Mal d 1, a ribonuclease, is a heat-sensitive allergen and belongs to the protein class of pathogenesis-related (PR) proteins. The allergen shares homologous IgE epitopes with major birch pollen allergen Bet v 1 and Cor a 1 from hazelnut pollen.
