Walnut ELISA

The MonoTrace Walnut ELISA kit can be used to detect and quantify the presence of walnut protein in complex food matrices or to check for the removal of potentially allergenic walnut protein residues after surface swabbing.

Walnuts are used extensively in foods, especially in baked goods, and are the leading cause of allergic reactions to Tree Nuts in the US. Walnut and Pecan are cross-reactive in many allergic individuals, but, compared to other detection methods, BioFront’s MonoTrace ELISA kit shows a higher degree of specificity to Walnut.

• Target major food allergens
• Robust assay with high specificity to target allergen
• Quantitative assay in 30 minutes
• Uniform extraction for multiple allergens
• Wide quantitative range (e.g., 1 – 40 ppm)
• Reduce food matrix interference and cross-reactivity
• Sensitivity at or below 1 ppm
• Ready-to-use Standards

MonoTrace ELISA kits represent the first comprehensive line of monoclonal antibody-based assays aimed at helping the food industry to accurately detect and quantify trace amounts of nut allergens in various food matrices. These ELISAs incorporate precisely defined sets
of monoclonal antibodies targeting major food allergens such as almond and provide quantitative results in just 30minutes post-extraction thanks to three 10-minute incubations!
• 10-minute sample incubation
• 10-minute conjugate incubation
• 10-minute substrate incubation

BioFront Technologies has developed the first comprehensive line of monoclonal antibody-based ELISA assay kits (MonoTrace ELISAs) for the detection of food allergen contamination in various food samples and on environmental surfaces. The MonoTrace Walnut ELISA incorporates the use of a precisely defined set of handpicked monoclonal antibodies selected after a rigorous screening process for their ability to:

  • Target a highly stable Walnut allergen resistant to food processing effects
  • Recognize a carefully selected target protein to eliminate cross-reactivity and reduce the possibility of ‘false positive’ results
  • Perform well in a wide variety of food products with negligible food matrix interference
