  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

    Specialist using "QIAsymphony", an automation platform for molecular diagnostic tests. Molecular diagnostics is a collection of techniques used to analyze biological markers in the genome and proteome, and how their cells express their genes as proteins, applying molecular biology to medical testing.

  4. 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 ...

  5. 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 ...

  6. 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.

  7. Protein-fragment complementation assay - Wikipedia

    en.wikipedia.org/wiki/Protein-fragment...

    Interaction between the bait and the prey proteins brings the fragments of the reporter protein in close proximity to allow them to form a functional reporter protein whose activity can be measured. This principle can be applied to many different reporter proteins and is also the basis for the yeast two-hybrid system, an archetypical PCA assay.

  8. 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]

  9. Animal testing - Wikipedia

    en.wikipedia.org/wiki/Animal_testing

    The terms animal testing, animal experimentation, animal research, in vivo testing, and vivisection have similar denotations but different connotations.Literally, "vivisection" means "live sectioning" of an animal, and historically referred only to experiments that involved the dissection of live animals.
