Targeted Quantitative SCFA Analysis
Accurate quantification of key SCFAs, including acetate, propionate, and butyrate, in biological samples such as plasma, serum, feces, and tissue.
Our services have earned the trust of companies, schools, and organizations globally, and we remain dedicated to maintaining that trust.
Short Chain Fatty Acids (SCFAs) are saturated aliphatic monocarboxylic acids with fewer than six carbon atoms, primarily produced through microbial fermentation of dietary fibers in the gut. SCFAs play essential roles in host metabolism, immune modulation, and gut health. Common SCFAs include acetate, propionate, and butyrate, which influence energy homeostasis, inflammation, and microbial balance. Their precise quantification is critical in research fields such as nutrition, microbiome studies, and metabolic health.

Should samples be processed immediately after collection? How to prevent SCFA degradation?
SCFAs are volatile and susceptible to microbial metabolism, so prompt processing is essential.
How do SCFA extraction methods differ for various sample types (feces, serum, tissue)?
Why is derivatization necessary? What are the advantages of different derivatization reagents?
SCFAs have high polarity and volatility, making direct detection challenging due to peak overlapping and low sensitivity.
Which method is better for SCFA detection: GC-MS or HPLC?
How to assess the reliability of SCFA analysis results?
Why might low-abundance SCFAs (e.g., isovalerate) not be detected?
How can SCFA results be interpreted alongside gut microbiota data?
How to choose internal standards? What are common issues?
Recommended Internal Standards: Butyrate-d4, 2-methylpentanoic acid, selected based on similar physicochemical properties to SCFAs.
Common Issues:
What key information should be included in the data report?
