Trimethylamine-N-Oxide(TMAO) in Serum/Plasma LC-MS/MS Analysis Kit

The human gut contains a complex and metabolically active microbial ecosystem (microbiota). The gut microbiome has recently been proven to play an important role in cardiovascular disease and various other disorders. Among the microbiome-related metabolites, trimethylamine-N-oxide (TMAO) has drawn a lot of attention owing to its proatherogenic and prothrombotic properties. Thus, abnormality in circulating level of TMAO could be a risk factor for certain diseases.

  • Highlights

    Quantitative analysis of TMAO in 5 min. for serum/plasma.

    Just a few pipetting steps for the sample preparation; for plasma/serum-protein crash and shoot.

    Safeguarded by its own stable labelled isotope (TMAO-D9) as internal standard.

    Consuming small volume of patient’s sample.

    Long life span of HPLC column.
  • Parameters
