Short-chain fatty acids (SCFA), also known as volatile fatty acids (VFAs), refer to organic fatty acids with 2-6 carbon atoms. SCFAs mainly include acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid, caproic acid and isohexanoic acid.
SCFAs can participate in the energy supply of intestinal epithelial cells, and gradually become signal molecules that regulate diet, intestinal microbes and the host. In the intestine, SCFAs can regulate intestinal immunity, glucose homeostasis, blood lipids, and reduce the risk of obesity and diabetes.
As the main energy substrate, SCFAs have anti-inflammatory and anti-cancer effects. SCFAs can affect chronic diseases through a variety of mechanisms, play an important role in maintaining the metabolic homeostasis of colonic epithelial cells, and protect the colon from external damage.
Creative Proteomics can provide you with one-stop high-sensitivity quantitative analysis of SCFAs, including SCFAs with C2-C12 carbon chain lengths of various biological materials (feces and serum, etc.).

Absolute quantification: Use external standard method to quantify, and use internal standard for correction, qualitative and quantitative is more accurate.
High sensitivity: we use gas chromatography hyphenated to triple quadrupole mass spectrometers for short chain fatty acids targeted lipidomics (Thermo Scientific TSQ 9000 triple quadrupole GC-MS/MS system).
Determination of short-chain fatty acids by GC-MS (Wang et al., 2020)
Quick-freeze in liquid nitrogen and store at -80°C, and send it on dry ice.
