  2. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    An assay (analysis) is never an isolated process, as it must be accompanied with pre- and post-analytic procedures. Both the communication order (the request to perform an assay plus related information) and the handling of the specimen itself (the collecting, documenting, transporting, and processing done before beginning the assay) are pre-analytic steps.

  3. Molecular diagnostics - Wikipedia

    en.wikipedia.org/wiki/Molecular_diagnostics

    Advances in molecular biology have helped show that some syndromes that were previously classed as a single disease are actually multiple subtypes with entirely different causes and treatments. Molecular diagnostics can help diagnose the subtype—for example of infections and cancers—or the genetic analysis of a disease with an inherited ...

  4. Bioassay - Wikipedia

    en.wikipedia.org/wiki/Bioassay

    If the measured response is binary, the assay is quantal; if not, it is quantitative. [3] A bioassay may be used to detect biological hazards or to give an assessment of the quality of a mixture. [4] A bioassay is often used to monitor water quality as well as wastewater discharges and its impact on the surroundings. [5]

  5. Immunoassay - Wikipedia

    en.wikipedia.org/wiki/Immunoassay

    The amount of labelled antibody on the site is then measured. It will be directly proportional to the concentration of the analyte because the labelled antibody will not bind if the analyte is not present in the unknown sample. This type of immunoassay is also known as a sandwich assay as the analyte is "sandwiched" between two antibodies.

    en.wikipedia.org/wiki/Project_Gutenberg

    Project Gutenberg (PG) is a volunteer effort to digitize and archive cultural works, as well as to "encourage the creation and distribution of eBooks." [2] It was founded in 1971 by American writer Michael S. Hart and is the oldest digital library. [3] Most of the items in its collection are the full texts of books or individual stories in the ...

  7. ELISA - Wikipedia

    en.wikipedia.org/wiki/ELISA

    As an analytical biochemistry assay and a "wet lab" technique, ELISA involves detection of an analyte (i.e., the specific substance whose presence is being quantitatively or qualitatively analyzed) in a liquid sample by a method that continues to use liquid reagents during the analysis (i.e., controlled sequence of biochemical reactions that will generate a signal which can be easily ...

    Back in the 1450s, when the Bible became the first major work printed in Europe with moveable metal type, Johannes Gutenberg was a man with a plan. The German inventor decided to make the most of ...

  9. Bioanalysis - Wikipedia

    en.wikipedia.org/wiki/Bioanalysis

    Initially, nonspecific assays were applied to measuring drugs in biological fluids. These were unable to discriminate between the drug and its metabolites; for example, aspirin (c. 1900) and sulfonamides (developed in the 1930s) were quantified by the use of colorimetric assays. Antibiotics were quantified by their ability to inhibit bacterial ...
