Biochemical techniques involve the use of methods to evaluate the composition and properties of biological samples. It has applications in different areas of biological sciences. The information gained from such analysis provide indication of the substances that are present (qualitative) or may specify the exact amount of the substances (quantitative) present in the sample.
In recent years, many methods have been developed for a widespread of analysis and are marketed as assay kits. The kits used as diagnostic tools range from some simple colorimetric assays to more sophisticated procedures involving antibodies or nucleic acids. The kits include all necessary standards and can be used in manual procedures or using an automated instrument. In biochemical and research laboratories, a biochemist should be able to efficiently handle techniques such as chromatography, centrifugation, electrophoresis and spectrophotometry as they are the major techniques used in biochemistry.
