Detection of DNA Strand Breaks in Analysis of Apoptosis by Flow- and Laser-Scanning Cytometryristic features of apoptotic cells (.,.). A widely used methodology to detect apoptotic cells, thus, relies on labeling DNA strand breaks in situ, within the nuclear chromatin, either with fluorochromes (.–.) or absorption dyes (.–.). The overview of the techniques (TUNEL techniques), which were dev

Labeling DNA Breaks , by Klenow Enzymeerg polymerase of .. Klenow is now usually obtained as a recombinant protein expressed from a truncated . gene (.). To polymerize the addition of nucleotides to the 3′-OH end of DNA, Klenow requires a single stranded DNA template and a DNA or RNA primer with a 3′−hydroxyl terminus. Klenow lacks the

Nick Translation at the Electron Microscopic Levelies on combined 5′→3′ polymerase and 5′→3′ exonuclease activities of . DNA polymerase I. If a nick or single strand break with a 3′ hydroxyl terminus is present in a duplex DNA molecule, the enzyme will translocate it, removing nucleotides ahead of it by 5′→3′ exonuclease activity and synthesizing t

DNA Ligation as a Method for Labeling Apoptotic Cells in Tissue Sectionshe ability of terminal deoxyribonucleotidyl transferase to add nucleotides to breaks in DNA, and has generally been termed TUNEL (terminal dUTP nick end labeling), although ISEL (. end labeling) would be a more appropriate description. During the late stages of apoptosis, nucleases are activated tha

Detection of Specific Double-Strand DNA Breaks and Apoptosis , Using T4 DNA LigaseYet historically, the labeling of DNA breaks . was most often limited to the identification of apoptotic cells. Consequently, the major techniques for analysis of DNA cleavage in tissue sections were initially developed for the visualization of apoptotic death. These assays rely on enzymatic labelin

The Comet Assayimplest form, cells are embedded in agarose on a microscope slide, immersed in a lysis solution to remove lipids and proteins, and exposed to a weak electric field to attract broken, negatively-charged DNA towards the anode. After electrophoresis, DNA is stained using a fluorescent dye, and viewed u
