Bile acids are derived from cholesterol and serve an important role in emulsifying and digesting lipids. In addition, bile acid metabolism is intimately involved with the microbiota, and bile acids have been shown to exhibit endocrine and metabolic activity via receptors like FXR and TGR5. Metabolon’s Bile Acids Targeted Panel measures all the major human and rodent primary and secondary bile acids as well as their glycine and taurine conjugates.
Metabolomics reveals biological insights otherwise unseen. For a successful metabolomics study, both small molecule discovery and the ability to dig deeper into specific biomarkers of interest are needed to uncover actionable insights that propel new therapeutic developments. A specific combination of liquid chromatography-mass spectrometry (LC-MS) technology and expertise is required to identify these biomarkers of interest and develop assays that are sensitive enough to explore them fully.
At Metabolon, we understand the crucial role targeted small molecule assays play in drug development, and we’ve established best-in-class expertise. Metabolon has developed quantitative assays for more than 900 biochemicals in over 20 different matrices, including more than 150 qualified and/or validated targeted biochemical assays for pharmaceutical and biotechnology research and development. These assays focus on specific metabolites or metabolic pathways and can be used to track biomarkers and enhance biological understanding across preclinical and clinical research.

cGood Clinical Practice (GCP) Assays. Lower Limit of Quantitation (LLOQ) stated is based on normalization using an average dry weight of feces. The actual measurement of the assay is the concentration of analyte in the OMNImet™·GUT tube containing human feces. Analyte concentrations in the OMNImet™·GUT tubes will be normalized by measured dry weight of feces unless otherwise requested.

Dysregulated metabolism is essential for the growth and proliferation of individual cancer cells, but the physiology of the patient is as much a part of the equation as the tumor. Metabolomics can both identify cancer-specific drug targets and assess the patient’s phenotype more broadly, addressing key questions such as: Who will respond to the therapy? How can we expand the pool of responders? How can we predict adverse events? Overall, metabolomics informs decision-making and positions development programs for success by providing a functional readout of the molecular phenotype.
Recognized for our cutting-edge approach to metabolomics, Metabolon has been a valued resource for COVID-19 researchers worldwide. Our actionable metabolomic insights have fueled pivotal and high-profile studies like the National Institute of Allergy and Infectious Diseases (NIAID) IMPACC study research to improve understanding of high-risk patients and the Institute for Systems Biology research to improve understanding of high-risk patients. These and other metabolomics projects with actionable insights at Metabolon are helping get closer to the phenotype and pressing forward on COVID-19 answers.
Diabetes is a serious metabolic condition affecting more than 37 million Americans and 460 million people worldwide according to the most recent report from the Centers for Disease Control. Despite being a worldwide epidemic, much remains unknown about individual risk factors for diabetes development, and research is currently being done to identify new and effective treatment for diabetes at all stages. By facilitating assessment of specific metabolic pathways impacted by diabetes, targeted metabolomics can be a critical tool used to identify biomarkers of disease development for early intervention and novel targets to control disease progression, as well for the development of new pharmaceuticals with specific mechanisms of action.
Much about digestive diseases remains a mystery. Digestive disease includes a broad range of gastrointestinal-related health issues, ranging from chronic constipation to gastrointestinal infections to viral hepatitis. Irritable bowel syndrome (IBS) is estimated to impact between 25 and 45 million Americans and about 10 to 15 percent of the population worldwide. Although the exact cause of IBS is unknown, diet and microbiome are recurring influences. The unique ability for metabolomics to illuminate function, including those of microorganisms inhabiting the digestive tract, makes the technology a valuable tool for understanding IBS and other digestive conditions.
The liver is the single most important regulator of metabolic homeostasis at the organismal level. That makes metabolomics an indispensable tool for capturing an integrative profile of an individual’s liver function. As the incidence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) continues to rise, researchers and health-care providers can look to Metabolon to provide much-needed non-invasive diagnostic and prognostic indicators as well as a fundamental understanding of pathological processes. The metabolome integrates an individual’s genetic makeup and gene expression profile with nongenetic factors such as diet, environmental exposures, and the microbiome. Therefore layering metabolomic analysis onto genomic and transcriptomic data provides the best opportunity to understand disease.
It is well-established that a low-carbohydrate, high-fat ketogenic diet (KD) can help treat refractory epilepsy, which affects more than a third of epileptic patients who don’t respond to existing anticonvulsive drugs. What scientists haven’t understood until recently is how this kind of diet translates to brain activity. The answer for this aspect of epilepsy lies in the gut microbiome. There are many other neurological disorders like Alzheimer’s disease, ALS, Parkinson’s disease, and more. While so much remains to be understood about brain science, we do know that metabolomics is uniquely poised to understand the brain because of the ability of metabolites, small molecules, to cross the blood-brain barrier providing unique insights.
Metabolomics can be essential for investigating the association between nutrition and health status, as metabolites represent a functional readout at the interface between diet and the complex metabolic systems that influence both health and disease. By illuminating the interactions of metabolites throughout the body within defined pathways, targeted metabolomics can help investigators gain new insights into the absorption and digestion of diet-derived macronutrients, monitor metabolism by various organ systems, and subsequently assess the underlying biology of various health and disease states.
Once you see the full value of metabolomics, the only remaining question is: who does it best? While many laboratories have metabolite profiling or analytical chemistry capabilities, comprehensive metabolomics technologies are extremely rare.
Accurate, unbiased metabolite identification across the entire metabolome introduces signal-to-noise challenges that very few labs are equipped to handle. Also, translating massive quantities of data into actionable information is slow, if not impossible, for most because proper interpretation takes two things that are in short supply: experience and a comprehensive database.
Using our robust platform and visualization tools, our experts are uniquely able to tell you more about your molecule and develop assay panels to help you zero in on the results you need.
