Fecal BAs were assessed by electrospray (ESI) mass spectrometry coupled to liquid chromatography (LC) with a tandem mass spectrometry (MS/MS) instrument (AB SCIEX, ThermoScientific, Waters) using a kit customized by Biocrates® (Biocrates® Bile Acids Kit), which enabled the absolute quantification of up to 20 different BA. Metabolomics (Bile Acids) Created By Mette Peters Mette The objective was to measure the levels of selected bile acids in 159 human plasma and serum samples using the Biocrates Bile Acids kit. Biocrates Bile Acids. A set of 9 human and mouse plasma samples was measured in replicates. 188 metabolites, which were ca-refully selected based on studies of the human blood metabolome. Liquid handling is done on ML Star Hamilton robot. BIOCRATES Life Sciences AG operates as a research and technology. Austrian BIOCRATES Life Sciences AG, internationally renowned developer and marketer of innovative targeted metabolomics solutions, further expands its range of metabolomics-based locale: session: 1 month: Used by the site to show content to users based on their selected location. The synthesis of primary bile acids, and the conjugation of bile acids with tauring and glycine, takes place in the liver. Bile acids are essential for regulating cholesterol metabolism and the intestinal digestion and absorption of fat. Assays are based on LC-MS/MS separation and detection (Agilent … Bile acids are an important test for monitoring normal liver function. 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 microbiota induces modifi cations (dehydroxylation and/or decon- BIOCRATES Life Sciences AG, Eduard-Bodem-Gasse 8, 6020 Innsbruck, Austria. An injection volume of 10 μL was used. Their signaling functions play an important role in chronic disorders, sepsis, or The Biocrates bile acid panel measures the concentration of 20 different 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. BioAssay Systems' Bile Acid Assay Kit (EFBA-100) provides a fluorimetric means to measure total bile acids. The nomeclature has been proposed by Hofmann et al. The firm products are absoluteIDQ p150 kit, p180 kit, sterio17 kit, steroid reagents, biocrates bile acids kit, and steroid kit. Samples were prepared using the Bile Acids kit (Biocrates Innsbruck, Austria) in strict accordance with their detailed protocol. 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 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. The novel Bile Acid kit developed by Biocrates allows to measure 20 bile acid metabolites with very high sensitivity (up to 3 nM). This assay does not measure bile acid sulfates, and measures only the twelve non-sulfated bile acids. The Biocrates® Bile Acids Kit is the fi rst ready to use solution to quantify 20 bile acids in a standardized and high throughput fashion. View Hartmut Glossmann’s professional profile on Relationship Science, the database of decision makers. Each kit provides sufficient reagents to perform up to 100 assays, including blanks, bile acid standards and unknown samples. . The bile acid kit provides simultaneous quantification of 22 bile acids (properties outlined in Table 6). Fluorescence intensity (530/585 nm) is linear to the bile acid concentration in the sample. Higher serum bile acid levels and an altered gut microbiome contribute to fibrogenesis, liver injury, and tumorigenesis in cirrhotic and noncirrhotic NASH-HCC. The Biocrates Bile Acids assay quantifies 20 bile acids, 16 of which are normally detected in human plasma. Cholic acid AbsoluteIDQ p180 (188) (Kit / Service) Our most frequently used targeted metabolomics discovery panel. 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).
