Cross-Reactivity Among Non-Plant Allergens While patterns of cross-reactivity are clear among many plants, this pattern may not be as obvious among other types of allergens. Cross-reactivity among mammalian or insect species is not well-defined. Certain allergenic proteins (e.g. albumin, lipocalin, tropomyosin) may contribute to cross-reactivity in some patients. Tropomysoin, for example, is a protein found… read more

Profilin & Pan-Allergens Cross-reactivity is often seen between unrelated species due to shared minor allergens such as Profilin. A minor allergen is an allergenic protein that has demonstrated clinical sensitivity in a minority of patients in a population. Common allergens that demonstrate clinical sensitivity across unrelated species are known as Pan-Allergens. Profilin is a structual… read more
