As a result, western blot analysis provides an orthogonal approach that can be used to both confirm the multiplex competitive ELISA while also providing additional insight into the protein/peptide profile of fermented-hydrolyzed foods. Limitations of western blot analysis often include lower sensitivity than the comparable competitive ELISA and problems quantitating gluten-derived peptides and proteins. Further, unlike the competitive ELISA, the western blot analyses distinguished between the presence of antigenic proteinaceous materials and false positives due to the presence of binding inhibitors (as observed with four soy-based sauces and one vinegar). Cluster analysis of the estimated gluten concentration values (based on western blot band intensities relative to intact gluten standards at 2.5 μg/mL and 100 μg/mL) and that of the relative response of the nine gluten-specific antibodies to different gluten proteins/peptides, distinguished among the different categories of fermented-hydrolyzed foods comparable to what was observed in the multiplex competitive ELISA. The protein/peptide profiles generated by the nine gluten-specific antibodies varied in size distribution and intensity dependent on the type of food, with minor differences between related products. Horseradish peroxidase (HRP) conjugated gluten-specific antibodies (G12, R5, 2D4, MIoBS, and Skerritt), from nine commercial gluten ELISA test kits, previously utilized in the development of a multiplex competitive ELISA for the detection of fermented-hydrolyzed gluten, were utilized in western blot analyses of 59 fermented-hydrolyzed foods from four food groups (beer, soy-based sauces, vinegar, and sourdough bread). ![]()
