Abstract
In this work, a monoclonal antibody called G12, raised against the most immunotoxic peptide to celiac disease patients, was used to develop a sandwich ELISA. Preliminary results on cross-reactivities, recoveries, and extraction methods of the new assay are presented. The assay calibration was performed using material from the Prolamin Working Group. The antibody's specificity was determined by cross-reactivity studies on different grains, nuts, oils, and starches. Recovery of the assay was determined by spiking experiments on common food matrixes, as well as on problematic matrixes. Furthermore, sample extraction methods using ethanol, cocktail solution, and a proprietary buffer have been compared.
