Following the ideas of genomics and proteomics, metabolomics is an emerging omics that is the qualitative and quantitative analysis of all metabolites in an organism to find the relationship between metabolites and physiological changes. Metabolomics is the study of endogenous small molecules with a relative molecular mass of less than 1500 Da, which analyzes the changes of metabolites of biological systems (cells, tissues, or organisms) after stimulation or disturbance.

Service Specifications

Untargeted metabolomics refers to the non-biased detection of the dynamic changes of all small molecule metabolites in cells, tissues, organs, or organisms after stimulation or disturbance by LC-MS, GC-MS, and NMR technology. Differential metabolites are screened by bioinformatics analysis, and then pathway analysis is performed to reveal the physiological mechanism of their changes.

Project Design
Untargeted metabolomics is used to detect and quantify total metabolites in biological samples. The design idea of untargeted metabolomics experiments is to compare differential metabolites under different treatments or physiological states and to explore the difference of mechanisms. At least 8 biological replicates are required for cell, plant, and microbial samples in each group. At least 10 biological replicates are required for animal samples in each group. At least 30 biological replicates are required for clinical samples each group.

Targeted metabolomics refers to several target compounds or target metabolites involved in a certain pathway. The targeted metabolomics method with high specificity, high sensitivity, and good reproducibility was established by using the standard compounds for absolute quantitative analysis of the target metabolites. Technique platforms include liquid chromatograph-mass spectrometer (LC-MS) and Selective Reaction Monitor / Multi Reaction Monitor (SRM/MRM).

    Project Design
    Targeted metabolomics analysis has several characteristics, such as high specificity, high sensitivity, and quantitative accuracy. It can be combined with other experimental data to reveal relevant molecular mechanisms by accurate quantitative and qualitative analysis of a specific metabolite. On the other hand, it can also provide strong supports for the development and utilization of metabolic biomarkers in the future. Targeted metabolomics can be used to test hypotheses proposed by untargeted metabolomics experiments.
