   Enzyme assay

   These types of assay can be extremely sensitive, since the light produced can be captured by photographic film over days or weeks, but can be hard to quantify, because not all the light released by a reaction will be detected. ... Radioactivity is usually measured in these procedures using a scintillation counter.
2. close

   Assay

   An assay is a procedure where a property or concentration of an analyte is measured. ... The standard traditions have a long history of reliability; "special" new methods frequently associate with reduced assay accuracy.
3. close

   Survivin

   It is known that intracellular proteases called caspases degrade the cellular contents of the cell by proteolysis upon activation of the death pathway. ... In a luciferase reporter assay, if the promoter is active, the luciferase gene is transcribed and translated into a product that gives off light that can measured quantitatively and thus represents the activity of the promoter.
4. close

   Thymidine kinase

   The enzyme is not set free from cells undergoing normal division where the cells have a special mechanism to degrade the proteins no longer needed after the cell divisionCite error: Invalid <ref> tag; refs with no name must have content. ... This assay gives a considerably more sensitive determination.
5. close

   SNP genotyping

   The intensity is then measured as temperature is increased until the Tm can be determined. ... Several developments have extended the original Invader assay.
6. close

   Bicinchoninic acid assay

   The total protein concentration is exhibited by a color change of the sample solution from green to purple in proportion to protein concentration, which can then be measured using colorimetric techniques. ... The BCA assay primarily relies on two reactions.
7. close

   CAP-e

   However, it performed beyond expectation in the ROS PMN assay where inhibition of ROS formation was measured at extremely low concentrations of Açai aqueous extract.
8. close

   Cytotoxicity

   One commonly measured molecule is lactate dehydrogenase (LDH). ... A similar redox-based assay has also been developed using the fluorescent dye, resazurin.
9. close

   MTT assay

   "Rapid colorimetric assay for cellular growth and survival: application to proliferation and cytotoxicity assays".
10. close

    K-Casein

    FTC-K-Casein Assay ... This variation allows quantification of the -casein molecules degraded in a more precise and specific way, detecting only those enzymes able to degrade such molecules.
