The nomeclature has been proposed by Hofmann et al. Cholic acid AbsoluteIDQ p180 (188) (Kit / Service) Our most frequently used targeted metabolomics discovery panel. Bile acid quantification was performed by the Sick Kids Analytical Facility for Molecules (AFBM) by liquid chromatography tandem mass spectrometry (LC-MS-MS) using the Biocrates® Life Sciences Bile Acids Kit (Biocrates, Innsbruck, Austria) according to the manufacturer’s instructions. This assay does not measure bile acid sulfates, and measures only the twelve non-sulfated bile acids. The lysine degradation product 2-aminoadipic acid is heavily decreased in concentration which already hints at a protective effect according to the authors. Bile acids are essential for regulating cholesterol metabolism and the intestinal digestion and absorption of fat. Bile acids were analyzed using the commercially available Biocrates Bile Acids Kit (Biocrates Life Science AG, Innsbruck, Austria) as described by Marksteiner et al. The Biocrates bile acid panel measures the concentration of 20 different bile acids. Introduction: Increasing evidence suggests a role for the gut microbiome in central nervous system disorders and a specific role for the gut-brain axis in neurodegeneration. Read user reviews, compare products & request pricing of BIOCRATES Life Sciences AG - ADME-Toxicology laboratory products & instrumentation. Samples: serum, plasma, urine and other biological samples. Bile acids are essential for regulating cholesterol metabolism and the intestinal digestion and absorption of fat. Bile acid is metabolized in the liver and is present in increased concentrations with abnormal liver function. BA quantification was performed by liquid chromatography tandem mass spectrometry using the Biocrates Life Sciences Bile Acids Kit (BIOCRATES Life Science AG, Innsbruck, Austria) according to manufacturer's instructions (see Table 3 for list of BAs, abbreviations, and their levels across diagnosis groups). The bile acid kit provides simultaneous quantification of 22 bile acids (properties outlined in Table 6). Assays are based on LC-MS/MS separation and detection (Agilent … The Biocrates Bile Acids assay quantifies 20 bile acids, 16 of which are normally detected in human plasma. Bile Acid Kit (20) (Kit / Service) Bile acids are important indicators of the hepato-biliary function as well as the gut microbiome. Biocrates© Bile Acids Kit (96 wells) - Waters for up to 84 samples; for HPLC and UHPLC pump System Appelez-nous : +33 (0)2.32.64.45.45 Liste des fabricants Site instrumentation Biocrates Bile Acids. Liquid handling is done on ML Star Hamilton robot. The MxP Quant 500 kit combines LC-MS/MS of 13 compound classes, basically small molecules, bile acids, and free fatty acids, followed by FIA-MS/MS of 12 lipid classes (including acylcarnitines) and hexoses, into a single workflow (Figure 1). The microbiota induces modifi cations (dehydroxylation and/or decon- Each kit provides sufficient reagents to perform up to 100 assays, including blanks, bile acid standards and unknown samples. A set of 9 human and mouse plasma samples was measured in replicates. . This assay can be used to measure bile acid concentrations in mice in a wide variety of applications including mouse serum, liver, bile, feces, and intestine. The complete analytical process (Data processing, sample registration, work list generation) was accomplished using the MetIDQ™ software package, which is an integral part of the Biocrates ® Bile Acid Kit. spectrometer (Waters Inc., Milford, Massachusetts, USA). [16]. Samples were prepared using the Bile Acids kit (Biocrates Innsbruck, Austria) in strict accordance with their detailed protocol. The major bile acid is cholic acid, which can be conjugated or unconjugated forming different isoforms: deoxy-glyco-cheno-lith-hyo-tauro or urso.
