Recombinant Peanut Ara h2

Regular price $225.00

Peanut (Arachis hypogaea) is one of the most common food allergens that can induce fatal anaphylaxis, and Ara h 2 is one of the major allergen components involved in peanut allergy (1). It tends to present early in life, it does not usually resolve, and in highly sensitized people trace quantities can induce an allergic reaction (2). 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 (3)
