    Untargeted Metabolomics Service

      Untargeted metabolomics is a study in which all detectable metabolites are identified and quantitated for analyzing the overall metabolic characteristics and discovering metabolic mechanisms behind the phenomenon. Also known as discovery metabolomics, untargeted metabolomics is a powerful tool for large-scale early phase diagnosis and discovery of new biomarkers. Compared to traditional metabolic quantitation methods, untargeted metabolomics is a high-throughput technology, enabling more comprehensive analysis with more accurate data acquisition, eliminating biased research direction.

      MtoZ Biolabs offers untargeted metabolomics analysis service using an LC-MS-based multiple reaction monitoring (MRM) and GC-MS-based single ion monitoring (SIM) metabolomics platforms.

      Sample Types



      Sample Submission Requirements

      1. Cells and Microbes Samples

      Cellular activities should be terminated instantly, whereas the cells remain intact.


      2. Animal Body Fluids Samples

      Such as urine, blood, saliva, etc. Samples must be added with anticoagulant and preservative reagents right after sample collection, followed by freezing at -80 °C.


      3. Plant Tissues

      200 mg/sample. Samples should be frozen in liquid nitrogen right after sample collection, and then transferred to -80 °C for storage.


      4. Serum Samples

      Repeated freezing and thawing of sample must be eliminated. Serum samples should be settled down at room temperature for 30 min in the collection tube, and then transferred to centrifuge tube and centrifuged at 8,000 rpm for 5 min. After centrifugation, supernatant is aliquoted to freezing tubes with 500 uL/sample, and stored at -80 °C.


      5. Urine Samples

      1 mL/sample. Urine samples can be aliquoted to centrifuge tubes with 1 mL each tube and addition of 1/100 (w/v) sodium azide, and stored at -80 °C.


      6. Faeces samples

      10 mg/sample



      1. Experiment Procedures

      2. Parameters of Liquid Chromatography and Mass Spectrometer

      3. MS Raw Data Files

      4. MS Data Quality Checks

      5. Metabolites Quantification Data

      6. Bioinformatics Analysis (PCA, KEGG, etc)

    • • Serum Metabolomics Service

      Human blood, as an important fluid sample in metabolomics, is mainly divided into plasma and serum. Compared to plasma, serum does not contain fibrinogen, and its components are relatively simple with over 1000 kinds of endogenous small molecule metabolites, making it an important metabolomics fluid sample. Due to the variety and extensive range of polarities of small molecule metabolites in serum, including highly polar substances such as amino acids, glucose, and nucleosides, as well as low-polarity......

    • • Urine Metabolomics Analysis Service

      Urine contains a vast array of chemicals, including microbial metabolites and mammalian metabolic products. Drugs, pollutants, and industrial chemicals may also be present in urine. Since urine lacks homeostatic regulation, it can reflect metabolic disturbances, providing insights into systemic changes in response to physiological challenges or disease progression.

    • • Body Fluid Metabolomics Analysis Service

      Body fluid metabolomics is an important branch of metabolomics. It focuses on animal body fluids, evaluating the impact of endogenous stimuli (such as drugs or toxins) on the body by qualitatively and quantitatively analyzing changes in endogenous metabolites within biological systems. Human metabolism involves a series of complex biophysical and biochemical reactions. The volume, electrolyte concentration, osmotic pressure, and pH of intracellular and extracellular fluids continuously influence cellu......

    • • Exosome Untargeted Metabolomics Analysis Service

      Exosome (EX) is a heterogeneous group of extracellular vesicle (EV) with size similar to viruses (30-150 nm). Many different cell types, including red blood cells, B cells, T cells, mast cells, platelets, endothelial cells, fibroblasts, adipocytes, epithelial cells, muscle, dendritic cells, and tumor cells, can release EX. The heterogeneous vesicle is exclusively formed by the fusion of multivesicular bady formed by the inward budding of the endosomal membrane with the plasma membrane, which are then ......

    • • Cerebrospinal Fluid Untargeted Metabolomics Analysis Service

      Cerebrospinal fluid (CSF) is secreted within the central nervous system (CNS) and fills in the ventricles, the subarachnoid space of the brain, and the spinal column. CSF's role is to protect the brain from physical impacts. Furthermore, CSF plays a crucial role in the circulation of nutrients and chemicals in the blood and in waste management by actively transporting or facilitating bulk flow (from the extracellular fluid of the brain to the subarachnoid space
