  2. Diagnostic microbiology - Wikipedia

    en.wikipedia.org/wiki/Diagnostic_Microbiology

    The catalase test tests whether a microbe produces the enzyme catalase, which catalyzes the breakdown of hydrogen peroxide. Smearing a colony sample onto a glass slide and adding a solution of hydrogen peroxide (3% H 2 O 2) will indicate whether the enzyme is present or not. Bubbling is a positive test while nothing happening is a negative ...

  3. Bioassay - Wikipedia

    en.wikipedia.org/wiki/Bioassay

    Ames test procedure. One classical bioassay is the Ames test. A strain of Salmonella that requires histidine to grow is put on two plates with growth medium containing minimal amounts of histidine and some rat liver extract (to mimick liver metabolism). A suspected mutagen is added to one plate. If the plate with the suspected mutagen grows ...

  4. Bioburden - Wikipedia

    en.wikipedia.org/wiki/Bioburden

    The United States Pharmacopeia (USP) outlines several tests that can be done to quantitatively determine the bioburden of non-sterile drug products. [4] It is important when conducting these tests to ensure that the testing method does not either introduce bacteria into the test sample or kill bacteria in the test sample. [4]

  5. Assay - Wikipedia

    en.wikipedia.org/wiki/Assay

    The analyte can be a drug, biochemical substance, chemical element or compound, or cell in an organism or organic sample. [ 1 ] [ 2 ] An assay usually aims to measure an analyte's intensive property and express it in the relevant measurement unit (e.g. molarity , density , functional activity in enzyme international units, degree of effect in ...

  6. Microtox bioassay - Wikipedia

    en.wikipedia.org/wiki/Microtox_bioassay

    Microtox is an in vitro testing system which uses bioluminescent bacteria (Allivibrio fischeri, formerly known as Vibrio fischeri) to detect toxic substances in different substrates such as water, air, soils and sediments. [1] Allivibrio fischeri are non-pathogenic, marine, bacteria that luminesce as a natural part of their metabolism. [2]

    en.wikipedia.org/wiki/List_of_reagents

    the central organic synthesis reagent for hydroboration Dicyclohexylcarbodiimide: an organic compound; primary use is to couple amino acids during artificial peptide synthesis Diethyl azodicarboxylate: a valuable reagent but also quite dangerous and explodes upon heating Diethyl ether: organic compound; a common laboratory solvent Dihydropyran

  8. In vitro - Wikipedia

    en.wikipedia.org/wiki/In_vitro

    In vitro testing has been used to characterize specific adsorption, distribution, metabolism, and excretion processes of drugs or general chemicals inside a living organism; for example, Caco-2 cell experiments can be performed to estimate the absorption of compounds through the lining of the gastrointestinal tract; [20] The partitioning of the ...

  9. Microbiological culture - Wikipedia

    en.wikipedia.org/wiki/Microbiological_culture

    Motile bacteria (left) will grow out from the stab line while non-motile bacteria (right) are present only along the stab line. Stab cultures are similar to agar plates, but are formed by solid agar in a test tube. Bacteria is introduced via an inoculation needle or a pipette tip being stabbed
