  2. Molecular-weight size marker - Wikipedia

    en.wikipedia.org/wiki/Molecular-weight_size_marker

    A molecular-weight size marker, also referred to as a protein ladder, DNA ladder, or RNA ladder, is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix.

  3. DNA laddering - Wikipedia

    en.wikipedia.org/wiki/DNA_laddering

    DNA laddering (left) visualised in an agarose gel by ethidium bromide staining. A 1 kb marker (middle) and control DNA (right) are included.. DNA laddering is a feature that can be observed when DNA fragments, resulting from Apoptosis DNA fragmentation are visualized after separation by gel electrophoresis the first described in 1980 by Andrew Wyllie at the University Edinburgh medical school ...

  4. Apoptotic DNA fragmentation - Wikipedia

    en.wikipedia.org/wiki/Apoptotic_DNA_fragmentation

    The apoptotic DNA fragmentation is being used as a marker of apoptosis and for identification of apoptotic cells either via the DNA laddering assay, [2] the TUNEL assay, [3] [4] or the by detection of cells with fractional DNA content ("sub G 1 cells") on DNA content frequency histograms e.g. as in the Nicoletti assay.

  5. Complement-dependent cytotoxicity - Wikipedia

    en.wikipedia.org/wiki/Complement-dependent_cyto...

    Complement-dependent cytotoxicity (CDC) is an effector function of IgG and IgM antibodies.When they are bound to surface antigen on target cell (e.g. bacterial or viral infected cell), the classical complement pathway is triggered by bonding protein C1q to these antibodies, resulting in formation of a membrane attack complex (MAC) and target cell lysis.

  6. DNA Specimen Provenance Assignment - Wikipedia

    en.wikipedia.org/wiki/DNA_Specimen_Provenance...

    DNA Specimen Provenance Assay (Assignment) (DSPA) testing can be performed on specimens from a range of medical specialty areas, such as gastroenterology, obstetrics, pulmonology, radiology, urology, etc. Molecular methods are currently available to extract DNA from a variety of sources, including fresh tissue, formalin-fixed, paraffin-embedded ...

  7. Molecular diagnostics - Wikipedia

    en.wikipedia.org/wiki/Molecular_diagnostics

    For example, the ColoGuard test may be used to screen people over 55 years old for colorectal cancer. [57] Cancer is a longtime-scale disease with various progression steps, molecular diagnostics tools can be used for prognosis of cancer progression. For example, the OncoType Dx test by Genomic Health can estimate risk of breast cancer.

  8. Genotoxicity - Wikipedia

    en.wikipedia.org/wiki/Genotoxicity

    Tobacco smoke is the main cause of lung cancer. Risk estimates for lung cancer indicate that tobacco smoke is responsible for 90% of lung cancers in the United States. Tobacco smoke contains more than 5,300 identified chemicals. The most significant carcinogens in tobacco smoke have been determined by a "Margin of Exposure" approach. [13]

  9. Genetic testing - Wikipedia

    en.wikipedia.org/wiki/Genetic_testing

    Test results can be retrieved within 7–14 days after the test is done. This method is 99.4% accurate at detecting and diagnosing fetal chromosome abnormalities. There is a slight risk of miscarriage with this test, about 1:400. Another method of prenatal testing is chorionic villus sampling (CVS). Chorionic villi are projections from the ...
