Used in research to detect and quantify 3-methylindole (also known as skatole) in biological samples such as serum, plasma, and tissue extracts. This ELISA kit is particularly useful in studies related to gut health, microbial metabolism, and odorant production in livestock. It enables scientists to assess the levels of faecal-derived compounds linked to intestinal function and disease. Commonly applied in agricultural and biomedical research to investigate the role of 3-methylindole in conditions like boar taint, inflammatory bowel disease, and environmental odor control. The assay provides a sensitive and specific method for high-throughput analysis without the need for complex instrumentation like mass spectrometry.
