    Untargeted Lipidomics Analysis Service

      Lipids are the main components of biological membranes. Lipids are not only the main form of energy storage in living cells but also serve as mediators of cell signaling. The lipidome consists of 8 major classes, over 80 main categories, 300 subclasses, and thousands of lipids at different concentrations. Lipidomics is the systematic study of all lipid molecules (> 30,000 species) within a biological system, tissue, body fluid, or cell. Comprehensive identification and precise quantification of lipids are crucial for understanding cellular physiology and pathophysiology in lipidomics research.


      Non-targeted lipidomics can analyze hundreds to thousands of different lipids simultaneously, which is valuable for assessing an individual's health condition. Lipidomic differences have been widely used in studies of cancer, diabetes, Alzheimer's disease, and cardiovascular diseases. These detailed lipid profiles can be used to evaluate medical risks, monitor, and optimize patient treatment, forming the basis of the concept of precision medicine. The applications of non-targeted lipidomics include agricultural science, biomarkers, Alzheimer's disease, atherosclerosis, cardiovascular diseases, cancer, diabetes, obesity research, clinical diagnostics, drug discovery, and systems biology.


      Although lipids are major components of the metabolome, the insolubility of many lipids in aqueous solutions necessitates different methods from those used for more water-soluble components in metabolomics. Mass spectrometry (MS) is the primary analytical platform for lipidomics, and nuclear magnetic resonance (NMR) is also widely used in metabolomics. Gas chromatography-mass spectrometry (GC-MS) was the main tool for lipid analysis in the past, replaced by desorption ionization techniques connected to MS such as atmospheric pressure ionization (API) and matrix-assisted laser desorption ionization (MALDI). API is usually electrospray ionization (ESI), often coupled with a liquid chromatography (LC) system for sample separation before MS analysis. MALDI is mainly performed under vacuum, typically not connected with an LC separation system, but can be used in conjunction with thin-layer chromatography (TLC) plates. MALDI-MS imaging (MSI) is increasingly used in lipidomics analysis because it can provide spatial information of lipids within tissues. By measuring the mass-to-charge ratio (m/z) of ionized substances, MS can provide molecular weight information. Many modern mass spectrometers can achieve mass accuracy of 0.001-0.002 m/z, allowing lipid profiles to be matched in databases through m/z searches or identification of ionized molecules using various commercial or open-source software. Tandem mass spectrometry (MS/MS) or multistage fragmentation (MSn) experiments can provide structural information.


      MtoZ Biolabs offers reliable, rapid, and cost-effective UPLC-Q-TOF non-targeted lipidomics services based on high stability, repeatability, and sensitivity of the separation, characterization, identification, and quantification systems.

    • • Yeast Non-Targeted Lipidomics Analysis Service

      Saccharomyces cerevisiae, commonly known as brewer's yeast, serves as a model organism for exploring eukaryotic cell physiology and molecular events. It has facilitated groundbreaking studies in transcriptomics, proteomics, and interactomics. The field dedicated to the study of yeast lipids is termed "yeast lipidomics." Brewer's yeast features a relatively straightforward lipidome, comprising approximately 150 lipid molecules identified to date.

    • • Plant Non-Targeted Lipidomics Analysis Service

      Lipids play an important role in plants, serving as structural components of cell membranes, main storage substances in seeds, pigments for energy capture in leaves, and signaling molecules for cell communication.With the development of lipidomics, the mass spectrometric analysis of plant lipids has been significantly improved. Plant lipidomics is defined as the analysis of plant lipids using mass spectrometry.

    • • Mammalian Non-Targeted Lipidomics Analysis Service

      As the main components of cell membranes and energy sources, lipids play a significant role in both cellular and physiological energy homeostasis. The primary biological functions of lipids include energy storage, signal transduction, and serving as structural components of cell membranes. The composition of lipids varies among different tissues. In animal tissues, the composition of structural lipids (such as phospholipids) is relatively constant under normal physiological conditions.
