  2. Bioassay - Wikipedia

    en.wikipedia.org/wiki/Bioassay

    A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured relative to a standard compound. [3] [1] A typical bioassay involves a stimulus (ex. drugs) applied to a subject (ex. animals, tissues, plants). The corresponding response (ex. death) of the subject is thereby triggered and ...

  3. Diagnostic microbiology - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_Microbiology

    The principle behind this test is to use enzymes native to the organism to create a colored product in the presence of foreign molecules. The chemical 5-bromo-4-chloro-3-indolyl-beta-D-galactoside is used in the test because N. lactamica can hydrolyze it with the production of β- galactosidase , turning the solution into a blue color.

    Ames test – salmonella bacteria is exposed to a chemical under question (a food additive, for example), and changes in the way the bacteria grows are measured. This test is useful for screening chemicals to see if they mutate the structure of DNA and by extension identifying their potential to cause cancer in humans.

  5. Adamkiewicz reaction - Wikipedia

    en.wikipedia.org/wiki/Adamkiewicz_reaction

    The Adamkiewicz reaction is part of a biochemical test used to detect the presence of the amino acid tryptophan in proteins. When concentrated sulfuric acid is combined with a solution of protein and glyoxylic acid, a red/purple colour is produced. It was named after its discoverer, Albert Wojciech Adamkiewicz.

  6. 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 ...

    Student's t-test, Analysis of variance, Mann–Whitney U test: Repeated measures design: A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods. [1] Paired t-test, Wilcoxon signed-rank test

  8. Biochemistry - Wikipedia

    en.wikipedia.org/wiki/Biochemistry

    Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research. [2] Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells, [ 3 ] in turn relating greatly to the understanding ...
