Allergen Information
MUXF3 is a cross-reactive carbohydrate structure present in a glycopeptide isolated from the glycoprotein bromelain from pineapple stem. It represents CCDs found across the plant kingdom and in insect venoms (Kamath 2023).
Clinical relevance
The clinical relevance of MUXF3 is considered negligible as no significant allergic responses associated with IgE to this epitope alone have been observed (Altmann 2007, Mari 2008, Amoah 2013).
Cross-reactivity
MUXF3 IgE has been shown to exhibit cross-reactivity with several plant-derived aeroallergens, food allergens, and allergens from venom and latex.
