Description

Gliadin Peptide A (206-217) is a defined synthetic peptide fragment corresponding to a specific sequence of the gliadin protein. This high-purity reference standard is critical for research and development in the field of celiac disease and gluten sensitivity. It is primarily utilized by pharmaceutical, diagnostic, and academic research laboratories for epitope mapping, antibody characterization, and the development of novel therapeutic and diagnostic assays.

Application

• Celiac Disease Research: Used as a key antigen for studying immune responses and T-cell epitope mapping related to gluten intolerance.
• Diagnostic Assay Development: Serves as a critical component in the development and calibration of ELISA kits and other immunoassays for detecting anti-gliadin antibodies.
• Therapeutic Vaccine Research: Employed in preclinical studies for the design and testing of potential peptide-based vaccines or tolerizing therapies for celiac disease.
• Biochemical Standard: Acts as a purified reference standard for quality control and method validation in analytical laboratories.
• Antibody Production & Characterization: Used to generate and screen monoclonal or polyclonal antibodies specific to gliadin epitopes.
