Used for the detection and quantification of zein, a storage protein found in corn, in various samples such as food products, plant extracts, and processed materials. The kit is particularly useful in food safety and allergen testing, helping to identify potential corn allergens in manufactured goods. It enables researchers and quality control laboratories to monitor cross-contamination in food processing environments and ensure compliance with labeling regulations for allergens. The assay provides a sensitive and specific method for measuring zein levels, supporting research in plant biology, food science, and immunology.
