Based on gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) technologies, Creative Proteomics provides fast and accurate qualitative and quantitative analysis of a variety of short-chain fatty acids (SCFAs) to meet your different needs.

Overview

SCFAs are mainly produced by the digestion of indigestible sugars such as dietary fiber, resistant starch, oligosaccharides, etc. in the colon by the fermentation of beneficial bacteria such as lactic acid bacteria and bifidobacteria.

SCFAs are gradually becoming known as signal molecules that regulate diet, intestinal microbes and the host. SCFAs can maintain the electrolyte balance in the intestine, induce cancer cell differentiation and apoptosis, and regulate gene expression. It can improve body composition, glucose homeostasis, blood lipid profile, reduce weight and colon cancer risk. As the main energy substrate, SCFAs can also have anti-inflammatory and anti-cancer effects. It also affects chronic diseases through various mechanisms, and plays an important role in maintaining the metabolic homeostasis of colonic epithelial cells, which can protect the colon from external damage and have a potentially positive impact on colon diseases.

Based on GC-MS and LC-MS technologies, we developed an analysis platform for SCFAs analysis. The external standard method is used to quantify the SCFAs, and the internal standard is used to calibrate the SCFAs, which can achieve the absolute quantity. Our short-chain fatty acid analysis services can be applied to many industries, including biomedicine, pharmaceuticals, agriculture, animal husbandry, food, nutrition and other fields.

Service Workflow

To detect more than 15 short chain fatty acids, we follow the basic process shown below. At the same time, we will adjust the experimental method according to different natures of samples, since Creative Proteomics has developed multiple novel sample preparation techniques.
