  2. TUNEL assay - Wikipedia

    en.wikipedia.org/wiki/TUNEL_assay

    The fluorochrome-based TUNEL assay applicable for flow cytometry, combining the detection of DNA strand breaks with respect to the cell cycle-phase position, was originally developed by Gorczyca et al. [4] Concurrently, the avidin-peroxidase labeling assay applicable for light absorption microscope was described by Gavrieli et al. [5] Since 1992 the TUNEL has become one of the main methods for ...

  3. DNA fragmentation - Wikipedia

    en.wikipedia.org/wiki/DNA_fragmentation

    Apoptotic DNA fragmentation is a natural fragmentation that cells perform in apoptosis (programmed cell death). DNA fragmentation is a biochemical hallmark of apoptosis.In dying cells, DNA is cleaved by an endonuclease that fragments the chromatin into nucleosomal units, which are multiples of about 180-bp oligomers and appear as a DNA ladder when run on an agarose gel. [8]

  4. Sperm Chromatin Structure Assay - Wikipedia

    en.wikipedia.org/.../Sperm_Chromatin_Structure_Assay

    Sperm Chromatin Structure Assay (SCSA) is a diagnostic approach that detects sperm abnormality with a large extent of DNA fragmentation. [1] First described by Evenson in 1980, the assay is a flow cytometric test that detects the vulnerability of sperm DNA to acid-induced denaturation DNA in situ. [2]

  5. 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.

  6. Restriction digest - Wikipedia

    en.wikipedia.org/wiki/Restriction_digest

    A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation, though this term is used for other procedures as well. In a restriction digest, DNA molecules are cleaved at specific restriction sites of 4-12 nucleotides in length by use of restriction ...

  7. DRIP-seq - Wikipedia

    en.wikipedia.org/wiki/DRIP-seq

    Fragmented gDNA is incubated with the DNA-RNA structure-specific S9.6 mAb. This step is unique for the DRIP-seq protocol, since it entirely relies on the high specificity and affinity of the S9.6 mAb for DNA-RNA hybrids. The antibody will recognize and bind these regions dispersed across the genome and will be used for immunoprecipitation.
