Soybean Allergy Related Epitopes

Kern, Karolin; Spiegel, Holger; Havenith, Heide; Szardenings, Michael
Nov 2018
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. Furthermore, the invention relates to the use of a peptide comprising a sequence element corresponding to an epitope for providing a molecule binding to a protein or peptide comprising the epitope.

High-Density Peptide Arrays for Malaria Vaccine Development

Loeffler, Felix F.; Pfeil, Johannes; Heiss, Kirsten
The development of an efficacious and practicable vaccine conferring sterile immunity towards a Plasmodium infection represents a not yet achieved goal. A crucial factor for the impact of a given anti-plasmodial subunit vaccine is the identification of the most potent parasitic components required to induce protection from both infection and disease. Here, we present a method based on a novel high-density peptide array technology that allows for a flexible readout of malaria antibodies. Peptide arrays applied as a screening method can be used to identify novel immunogenic antibody epitopes under a large number of potential antigens/peptides. Ultimately, discovered antigen candidates and/or epitope sequences can be translated into vaccine prototype design. The technology can be further utilized to unravel antibody-mediated immune responses (e.g., involved in the establishment of semi-immunity) and moreover to confirm vaccine potency during the process of clinical development by verifying the induced antibody responses following vaccination.
