Abstract: The present invention relates to the field of antibodies and their application in food and feedstuff quality control. In particular, the invention relates to a method for the manufacture of an antibody that specifically binds to soy Gly m 8 protein wherein said method comprises immunising an animal with the purified soy Glym8 protein, wherein said soy Glym8 protein has been obtained by expressing soy Glym8 protein in plants, and preferably, tobacco plants and purifying the soy Glym8 protein from said plants and, preferably, tobacco plants and obtaining an antibody from the animal which specifically bind to soy Gly m8 protein, wherein the animal will be sacrificed. Moreover, the invention contemplates an antibody obtained by said method as well as the use of said antibody for detecting soy material in a food preparation or feedstuff preparation. Further, a method for detecting soy material in a food preparation or feedstuff preparation and a kit for carrying out said method are provided.

Abstract: The invention relates to a compilation comprising at least five different peptides, each peptide comprising at least one sequence element corresponding to an epitope selected from the group consisting of SEQ ID NO.: 1-354, wherein at least five different epitopes are represented. The invention further relates to an in vitro method for determining a patient's immune status to soybean allergens, to a method for detecting at least one soybean allergen in a substance and to a method for determining the allergenicity of a soybean variety. Additionally, the invention relates to a kit comprising at least one composition containing a compound comprising at least five different sequence elements each corresponding to an epitope selected from the group consisting of SEQ ID NO.: 1-354, wherein at least five different epitopes are represented.
