Description

Allergen Gal D 4 (46-61) (Chicken) is a defined peptide sequence corresponding to a fragment of the chicken allergen Gal d 4, also known as lysozyme. This high-purity synthetic peptide is a critical reference standard and research tool for the study of food allergies, immunological responses, and epitope mapping. It is essential for laboratories and manufacturers in the diagnostics, pharmaceutical, and immunology research sectors who require precise and reliable materials to develop assays, validate testing methods, and advance therapeutic research.

Application

• Immunoassay Development & Calibration: Serves as a primary standard for the development and calibration of ELISA, immunoblot, and other immunoassays specific to chicken egg allergy.
• Allergenicity Research: Used in epitope mapping studies to understand the binding sites of IgE antibodies and the molecular basis of allergic reactions to chicken lysozyme.
• Diagnostic Kit Manufacturing: A key component in the production of in-vitro diagnostic (IVD) kits for the accurate detection and quantification of specific IgE against Gal d 4.
• Vaccine & Therapeutic Research: Employed in the research and development of hypoallergenic vaccines and immunotherapies for food allergy desensitization.
• Quality Control & Method Validation: Acts as a critical quality control material in laboratories to validate analytical methods and ensure the consistency of allergen testing.
• Biochemical & Structural Studies: Utilized in biochemical research to investigate protein-protein interactions, folding, and the functional properties of lysozyme fragments.
