Used for the detection and quantification of casein in various samples such as milk, dairy products, and food extracts. Commonly applied in food safety testing to identify potential allergen contamination, especially in products labeled as casein-free or dairy-free. Widely used in research settings to study protein composition and allergenicity. Enables high-throughput analysis in quality control laboratories due to its sensitivity and specificity. Suitable for monitoring casein levels during processing and storage to ensure product consistency and compliance with regulatory standards.
