Analytical Performance of Micro Pillar Array Columns (μPAC™) for Metabolic Profiling

PharmaFluidics
24 Jan 2018

Metabolic profiling studies have become indispensable in a wide range of research fields, they allow profound insights into the biochemistry of an organism at a certain moment. Liquid chromatography (LC) and mass spectrometry have become vital tools in these studies and more sensitive mass spectrometers alongside new or improved LC techniques allow scientists to retrieve more information from minute sampling amounts. In this study, plant extract samples are used to compare the analytical performance of a µPAC™ nano LC column to state-of-the-art ultra performance LC columns.

BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Toxicology / Drugs of Abuse TestingToxicology and Drugs of Abuse Testing is the investigation into toxic and illegal substances found at the scene of a crime or from a suspect and / or victim associated with a scene of a crime. Analyzers, immunoassays and drugs of abuse test kits and presumptive test kits are an essential aspect of toxicology investigation.Plant SciencePlant science studies the biology of plants, including genetics, physiology, ecology, and biotechnology. Research in this field is essential for improving crop yields, disease resistance, and sustainability.

It is widely used in fields like biochemistry, pharmaceuticals, and environmental analysis. By exploiting differences in the interaction of substances with a stationary phase and a mobile phase, chromatography enables precise purification and quantification of compounds. Whether you're working with complex biological samples or industrial chemicals, chromatography is essential for obtaining high-quality results. Browse our peer-reviewed product directory to find the best chromatography systems, compare products, read customer reviews, and get pricing directly from manufacturers.Drug DiscoveryDrug discovery is the process of identifying potential new medications, involving stages such as target identification, compound screening, and preclinical development. It relies on cutting-edge technologies like high-throughput screening, artificial intelligence, and molecular modeling to accelerate the identification of drug candidates. Drug discovery plays a pivotal role in developing new therapies for diseases ranging from cancer to rare genetic disorders. Browse our peer-reviewed product directory to find the latest drug discovery technologies, compare options, check customer feedback, and get pricing directly from manufacturers.Biomarker DiscoveryClinical biomarkers refer to substances related to known medical conditions that can be accurately measured <i>in vitro</i>. Biomarkers can be used to diagnose presence of a disease and indicate disease severity. The discovery of new biomarkers is incredibly valuable in the field of diagnostics.
