Recombinant Peanut Allergens Arah1 and Arah2

Peanut allergy is the most common type of food allergy that affects 4-8% of children and 1-2% of adults. It tends to present early in life, it does not usually resolve, and in highly sensitized people trace quantities can induce an allergic reaction. Among the peanut component proteins, IgE antibodies to Ara h2, and to a much lesser extent Ara h1, Ara h3, Ara h6, and Ara h9, have been identified as the major driver of clinically relevant allergy.
