BIOCRATES Life Sciences AG operates as a research and technology. The lysine degradation product 2-aminoadipic acid is heavily decreased in concentration which already hints at a protective effect according to the authors. spectrometer (Waters Inc., Milford, Massachusetts, USA). Each laboratory received a Biocrates ® Bile Acids Kit including system suitability test (SST) protocol. Sulfation of bile acids increases their solubility and decreases intestinal absorption, thereby enhancing fecal and urinary excretion. 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. 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. … A standardized quantitative Kit developed that allows the simultaneous analysis of 20 bile acids in 20 μL sample volume. 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.

The bile acid kit provides simultaneous quantification of 22 bile acids (properties outlined in Table 6). A set of 9 human and mouse plasma samples was measured in replicates. App Note. 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). Acute heart failure is characterized by a heavily reorganized metabolic phenotype especially in amino acids and lipids in … Assays are based on LC-MS/MS separation and detection (Agilent … Hartmut Glossmann is Co-Founder at BIOCRATES Life Sciences AG. Detection range: 1 - 150 µM bile acids. The BIOCRATES® Bile Acids Kit* is based on (ultra) high performance liquid chromatography coupled with electrospray tandem mass spectrometry (UHPLC-MS/MS) and is characterized by quick and highly effective sample extraction on a 96-well patented filter plate. Bile acid is metabolized in the liver and is present in increased concentrations with abnormal liver function. 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. Liquid handling is done on ML Star Hamilton robot. Total bile acid (TBA) level was calculated by summation of 15 conjugated and unconjugated primary and secondary BA levels. [16]. Each kit provides sufficient reagents to perform up to 100 assays, including blanks, bile acid standards and unknown samples. locale: session: 1 month: Used by the site to show content to users based on their selected location. Biocrates ® Bile Acids Kit - primary bile acids - secondary bile acids - human and rodent specific bile acids. BioAssay Systems' Bile Acid Assay Kit (EFBA-100) provides a fluorimetric means to measure total bile acids. Laboratories were first required to pass the acceptance criteria for the SST. 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. The kit has been validated according to the EMA guidelines for human and rat plasma. 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. There was no difference in incremental AUC 0–24 between the tolerant and intolerant cohorts for each individual bile acid, when corrected for multiple testing. The synthesis of primary bile acids, and the conjugation of bile acids with tauring and glycine, takes place in the liver. An injection volume of 10 μL was used. Samples: serum, plasma, urine and other biological samples. The nomeclature has been proposed by Hofmann et al. Bile Acid quantification – Biocrates AbsoluteIDQ - Bile Acids Kit. Cell Biolabs’ Total Bile Acid Assay Kit is a simple colorimetric assay that measures the amount of total bile acid present in plasma, serum, tissue homogenates, or cell lysates in a 96-well microtiter plate format. Bile acids are essential for regulating cholesterol metabolism and the intestinal digestion and absorption of fat.
