Metabolic flux analysis is a dynamic approach for understanding how metabolites move through biochemical pathways under specific genetic, nutritional, pharmacological, or environmental conditions. Unlike conventional metabolomics, which mainly measures metabolite abundance, metabolic flux analysis focuses on pathway activity, substrate utilization, carbon flow, metabolic rerouting, and functional changes in metabolic networks.
As a genetically tractable whole-animal model, Caenorhabditis elegans is highly suitable for metabolic flux studies in aging, nutrition, drug response, toxicology, metabolic disease research, and host-microbe interaction analysis. Its short lifecycle, conserved metabolic pathways, and compatibility with isotope tracing, omics profiling, and high-throughput phenotyping make it a valuable system for studying metabolic regulation at the organismal level.
CD BioSciences provides customized C. elegans Metabolic Flux Analysis Service to help researchers investigate how genes, diets, compounds, natural products, microbes, or toxicants reshape metabolic pathway activity. Our service integrates experimental design, isotope tracing, LC-MS/GC-MS-based detection, flux data interpretation, metabolic network analysis, and biological reporting to support both basic research and industrial applications.
Introduction to C. elegans Metabolic Flux Analysis
Metabolic pathways are highly dynamic. A metabolite may remain stable in abundance while its production and consumption rates change dramatically. Therefore, metabolic flux analysis provides deeper functional insight than steady-state metabolite profiling alone. It can reveal whether a pathway is activated, suppressed, compensated, or redirected after a genetic perturbation, dietary change, drug treatment, or environmental exposure.
In C. elegans, metabolic flux analysis can be used to study central energy metabolism, lipid turnover, amino acid utilization, sterol-related metabolism, mitochondrial activity, and diet-derived nutrient contribution. These pathway-level readouts are particularly valuable for aging research, longevity compound discovery, functional food evaluation, metabolic disease modeling, and drug toxicity assessment.

What Flux Analysis Adds
Metabolomics tells researchers which metabolites are present and how their levels change. Flux analysis adds a dynamic layer by showing how fast metabolic pathways are operating and how substrates are routed through the network.
Key Output
Pathway activity, substrate contribution, metabolic rerouting, and flux-associated biomarkers.
Our Services
CD BioSciences provides customized C. elegans Metabolic Flux Analysis Service to help researchers investigate dynamic pathway activity, substrate utilization, metabolic rerouting, and treatment-induced metabolic remodeling in whole-animal models. According to different research objectives, we offer both non-targeted metabolic flux analysis and pathway-focused targeted metabolic flux analysis.
Non-Targeted Metabolic Flux Analysis
Suitable for exploratory studies where the key pathways are not predefined. This service helps discover global flux changes and candidate pathways affected by genetic, dietary, pharmacological, or environmental perturbations.
Available service items:
- Non-targeted metabolic flux analysis
- C14–C22 FFA MS metabolic flux analysis
- Triglyceride metabolic flux analysis
Targeted Metabolic Flux Analysis
Designed for pathway-focused studies that need to evaluate specific metabolic routes, validate pathway activity, or compare flux changes across treatment groups, mutant strains, aging models, or compound exposure conditions.
Available service items:
- TCA cycle targeted flux analysis
- Acyl-CoA targeted flux analysis
- Acyl-carnitine targeted flux analysis
- Cholesterol metabolism targeted flux analysis
Integrated Flux Data Analysis
For each project, we provide professional data analysis and biological interpretation to help clients connect metabolic flux changes with experimental phenotypes. Flux analysis can also be integrated with metabolomics, lipidomics, transcriptomics, proteomics, lifespan assays, locomotion assays, stress resistance assays, toxicity assays, or other C. elegans phenotype readouts.
Applications
