https://www.selleckchem.com/products/sw033291.html Metabolomics, lipidomics, and the study of cellular metabolism are gaining increasing interest particularly in the field of immunology, since the activation and effector functions of immune cells are profoundly controlled by changes in cellular metabolic asset. Among the different techniques that can be used for the evaluation of cellular metabolism, the Seahorse Extracellular Flux Analyzer allows the real time measurement of both glycolytic and mitochondrial respiration pathways in cells of interest, through the assessment of extracellular acidification and oxygen consumption rate. Metabolomics, on the other hand, is the high-throughput analysis of metabolites, i.e., the substrates, intermediates, and products of cellular metabolism, starting from biofluids, cells or tissues. The metabolome does not include lipids as their properties are different from water-soluble metabolites and are classified under the lipidome. Lipidomics analysis allows the identification and quantification of lipid species. Metabolomics and lipidomics are currently performed with mass-spectrometry coupled with liquid or gas chromatography (LC-MS or GC-MS) and/or nuclear-magnetic resonance (NMR). Here we describe the protocol for the evaluation of metabolic rate, metabolomics, and lipidomics in T cells, examining the detailed experimental approaches.The dynamic regulation of protein function by altered protein expression and post-translational modifications (PTMs) is essential for T cell function, but it has remained difficult to systemically quantify such events. Mass spectrometry (MS)-based proteomics has become a mainstream tool for comprehensive profiling of proteome and PTMs, especially with the development of multiplexed isobaric labeling methods, such as tandem mass tag (TMT), coupled with high-resolution two-dimensional liquid chromatography and tandem mass spectrometry (LC/LC-MS/MS). Here, we introduce a deep proteomics profiling pro
