Bioanalytical Techniques

Bioanalysis is a sub-discipline of analytical chemistry covering the quantitative measure of xenobiotics (drugs and their metabolites, and biological molecules in unnatural locations or concentrations) and biotics (macromolecules, proteins, DNA, massive molecule medication, metabolites) in biological systems. The common bioanalytical techniques used in bioanalytical studies are a) Chromatographic methods b) Hyphenated techniques C) Electrophoresis d) Mass spectrometry e) Ligand binding assays f) Nuclear Magnetic resonance. Liquid chromatography mass spectrometry, gas chromatography–mass spectrometry, liquid chromatography diode array detection and capillary electrophoresis mass spectrometry were included under Hyphenated techniques. High performance liquid chromatography, gas chromatography, ultra performance liquid chromatography, Supercritical fluid chromatography are included under Chromatographic methods. Dual polarisation interferometry, Enzyme-linked immunosorbent assay, magnetic immunoassay and radioimmunoassay are the bio analytical techniques which are included under Ligand binding assays. The most oftentimes used techniques are: Liquid chromatography as well as tandem mass spectrometry (LC-MS/MS) for 'small' molecules and enzyme-linked immunosorbent assay (ELISA) for macromolecules. The bioanalyst deals with advanced biological samples containing the analyte among various type of chemicals which will have an adverse impact on the correct and precise quantification of the analyte. As such, a large vary of techniques are applied to extract the analyte from its matrix. These include: macromolecule precipitation, Liquid liquid extraction, Solid section extraction. Bioanalytical laboratories typically influence giant numbers of samples, as an example ensuing from clinical trials. As such, machine-driven sample preparation ways and liquid-handling robots are ordinarily utilized to extend potency and cut back prices.
