Used in research and diagnostic laboratories to detect and quantify milk peroxidase levels in biological samples such as milk, whey, and dairy products. The kit is particularly useful in food science to monitor the efficiency of pasteurization, as LPO activity decreases with heat treatment. It helps assess the freshness and quality of milk by measuring enzyme activity, which correlates with microbial load and storage conditions. Also applied in immunology and allergen studies to understand immune responses to milk proteins. The ELISA format allows for high sensitivity, specificity, and throughput, making it suitable for both academic and industrial research.
