Used in biomedical research to quantify trimethylamine N-oxide (TMAO) levels in biological samples such as serum, plasma, and urine. This kit supports studies investigating the role of TMAO in cardiovascular diseases, chronic kidney disease, and metabolic disorders. It enables researchers to assess TMAO as a potential biomarker for atherosclerosis, heart failure, and stroke risk. Widely applied in clinical labs and pharmaceutical research for high-throughput screening and validation of therapeutic interventions targeting gut microbiota-dependent metabolites.
