To support microbiome research, Pine Lake Laboratories has available an assay for short chain fatty acids (acetic, butyric, and propionic acid) in feces. These targeted metabolites can be used as an indicator of microbiome activity in research subjects and as biomarkers to evaluate the effect of various pharmaceutical treatments during pre-clinical and clinical trials.   The method involves extracting the short chain fatty acids from feces then analysis by direct injection GC-MS.   This method has been used to support studies in both humans and multiple animal species.   For more information, please see the white paper in our technical library titled “Short Chain Fatty Acid Analysis”
