Recombinant allergen Ara h 9 for Arachis hypogaea (Peanut)

Arachis hypogaea

Ara h 9 is a lipid transfer protein (LTP) and a major allergen in peanut-allergic patients from the Mediterranean region. Nonspecific lipid transfer proteins (LTPs) represent potent pollen and food allergens. Exist two Ara h 9 isoforms: Ara h 9.01 and Ara h 9.02. The two Ara h 9 isoforms displayed similar IgE reactivity. CD spectroscopy revealed similar secondary structures between Ara h 9 and Pru p 3. The Ara h 9 isoforms showed 62–68% amino acid sequence identity with Pru p 3. In peanut-allergic patients with concomitant peach allergy, Ara h 9 showed a weaker allergenic potency than Pru p 3 in histamine release assays. Therefore, Ara h 9 can induce histamine release from basophils, but to a lesser extent than Pru p 3.
