Used in research and diagnostic laboratories to detect and quantify Escherichia coli antigens in various samples such as water, food, and clinical specimens. The kit enables rapid identification of E. coli contamination, supporting food safety testing, environmental monitoring, and infectious disease studies. It is particularly useful in detecting pathogenic strains in outbreak investigations and quality control processes. The assay format allows high-throughput analysis with reliable sensitivity and specificity, making it a standard tool in microbiological research.
