Guru contains structural information on allergens listed on the WHO/IUIS Allergen nomenclature database, along with 3D structures and unique search features, which will make Guru an essential tool for allergen researchers. Guru will be freely available on Android and iOS and will be launched at ISMA. Join us for the presentation. We would love to have your feedback and ideas for improvements. Help us strengthen the allergen community. Guru – it’s all about allergens!
