Feces Metabolomics Service
Online Inquiry
Fecal metabolomics is a new tool to explore the links between microbial composition, host phenotype and complex genetic traits. Creative Proteomics has built a metabolomic analysis platform for feces samples using high-resolution mass spectrometry. We will use the appropriate sample pretreatment protocol for your experimental purposes, significantly improving the accuracy of feces metabolite identification and quantification of metabolites.
What We Can Provide:
Untargeted metabolomics analysis:
- Metabolic profile analysis
- Screening for differential metabolites
- Metabolic pathway analysis of differential metabolites
- Discover new biomarkers

Sample Requirements
- Rat feces: ≥ 15-20 mg dry weight
- Mouse feces: ≥ 15-20 mg dry weight
- Human feces: a single histology of 200 mg or more is recommended.
Collection of stool samples in a sterile stool collector or other sterile utensils is required. Care should be taken to label the sample immediately and store it at low temperature, trying not to expose it to air for too long to avoid contamination and degradation. Before freezing the collected fresh stool, it is recommended to mix the sample with a sterile stick.
Deliverables
- Experimental procedure
- Parameters of liquid chromatography / gas chromatography and MS
- MS raw data files and MS data quality checks
- Bioinformatics analysis report
Turnaround time:1-4 weeks
