allergens. Because of this a individual could generate IgE to an allergen, which can not just react with the primary sensitizing allergen but, because of significant sequence homology and hence common epitopes, it may even react having a connected just one. This situation might manifest, by way of example, with allergens from phylogenetically associated species, for example house-dust mites and grass pollens, but cross-reactivity might also be evident in between allergens from phylogenetically dissimilar species.

The number may perhaps signify importance or chronology of discovery. Allergens may be renumbered to conform towards the purpose and number of a associated allergen. Variations within the molecular excess weight or charge of an allergen as a result of amino acid substitutions or glycosylation are referred to as isoallergens and therefore are selected by a decimal place accompanied by 4 digits (e.g. Phl p five.0102 and Phl p 5.0201).
