[Analysis of the electrophoretic profiles of the protein extracts of the species Manihot esculenta (Crantz, 1975), Persea Americana (Mill., 1768) and Actinidia delicious (A. Chevalier., 1984), and their association with the latex-fruit syndrome for searching for potential allergens].

When analyzing the relationship between the separated protein fractions and the latex allergens described in the literature, a possible association of 35% was found for the extracts of M. esculenta and P. Americana, and 10% for A. Delicious, with great relevance being the association found with the allergens Hev b 4, Hev b 2, Hev 8 and Hev b 11, which are involved in Latex-Fruit Syndrome. The electrophoretic profiles of the prepared extracts were determined and compared with the Latex allergens. This information generates a contribution for the development of new research and advances in the standardization of these extracts on a large scale and for their future use in diagnostic tests.
