Analysis of DNA Fragmentation Using Agarose Gel Electrophoresis (Subscription Required) - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4429

Category: Cell Biology and Cell Culture: Apoptosis Protocols: Apoptosis Analysis

Analysis of DNA Fragmentation Using Agarose Gel Electrophoresis Shailaja Kasibhatla et al. This protocol provides a qualitative method for assessing cell death by detecting DNA fragments using agarose gel electrophoresis. One of the classic features of apoptosis is the cleavage of the genomic DNA into oligonucleosomal fragments represented by multiples of 180-200 bp. Visualizing these fragments can aid in characterizing an apoptotic event. May be combined with more quantitative methods. - [Read Analysis of DNA Fragmentation Using Agarose Gel Electrophoresis (Subscription Required)]

Analysis of DNA Fragmentation Using Propidium Iodide (PI) Fluorescence of Individual Nuclei Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4430

Category: Cell Biology and Cell Culture: Flow Cytometry Protocols: DNA Staining Protocols for Flow Cytometry

This protocol provides a method for analysis of DNA fragmentation using flow cytometry after propidium iodide (PI) labeling of apoptotic nuclei. Apoptotic nuclei stain less than their normal counterparts because of diffusion of low-molecular-weight fragments out of the cells and/or chromatin condensation. - [Read Analysis of DNA Fragmentation Using Propidium Iodide (PI) Fluorescence of Individual Nuclei Protocol]

Analysis of DNA Fragmentation Using Propidium Iodide (PI) Staining After Ethanol Fixation Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4431

Category: Cell Biology and Cell Culture: Flow Cytometry Protocols: DNA Staining Protocols for Flow Cytometry

This protocol provides a method for analysis of DNA fragmentation using flow cytometry after propidium iodide (PI) labeling of fixed apoptotic cells. Flow cytometry reveals apoptotic nuclei in the subdiploid region of the cell cycle histogram... - [Read Analysis of DNA Fragmentation Using Propidium Iodide (PI) Staining After Ethanol Fixation Protocol]

Analysis Of DNA Fragmentation Using The JAM Assay (Subscription Required) - http://www.cshprotocols.org/cgi/content/extract/2006/1/pdb.prot4432

Category: Cell Biology and Cell Culture: Apoptosis Protocols: Apoptosis Analysis

Analysis of DNA Fragmentation Using the JAM Assay. By Shailaja Kasibhatla et al., The JAM assay is based on labeling nuclear DNA of cycling cells with [3H]thymidine and harvesting samples on glass fiber filters. Apoptosis will generate DNA fragments small enough to pass through the glass fiber filter, resulting in decreased radioactivity of the particular sample. Cell-mediated cytotoxicity or cell killing mediated by cytotoxic T lymphocytes (CTL) can also be measured by this technique. - [Read Analysis Of DNA Fragmentation Using The JAM Assay (Subscription Required)]

Chromatin Immunoprecipitation and Microarray-Based Analysis of Protein Location Protocol - http://www.nature.com/nprot/journal/v1/n2/abs/nprot.2006.98.html

Category: Immunology: Immunoprecipitation Protocols: Chromatin Immunoprecipitation Protocols

Genome-wide location analysis, also known as ChIP-Chip, combines chromatin immunoprecipitation and DNA microarray analysis to identify protein-DNA interactions that occur in living cells. Protein-DNA interactions are captured in vivo by chemical crosslinking. Cell lysis, DNA fragmentation and immunoaffinity purification of the desired protein will co-purify DNA fragments that are associated with that protein. - [Read Chromatin Immunoprecipitation and Microarray-Based Analysis of Protein Location Protocol]

Fragmentation of DNA by Nebulization Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4539

Category: Cloning Protocols

Protocol describes a method for DNA fragmentation by nebulization, in which the fine mist created by forcing a DNA solution through a small hole in the nebulizer unit is collected. The size of the fragments obtained by nebulization is determined chiefly by the speed at which the DNA solution passes through the hole, altering the pressure of the gas blowing through the nebulizer, the viscosity of the solution, and the temperature. - [Read Fragmentation of DNA by Nebulization Protocol]

Fragmentation of DNA by Sonication Protocol - http://www.cshprotocols.org/cgi/content/abstract/2006/23/pdb.prot4538

Category: Cloning Protocols

Protocol describes a method for DNA fragmentation by sonication. During sonication, DNA samples are subjected to hydrodynamic shearing by exposure to brief periods of sonication. DNA that has been sonicated for excessive periods of time is extremely difficult to clone. - [Read Fragmentation of DNA by Sonication Protocol]

Generation of a Library of Randomly Overlapping DNA Inserts Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/2/pdb.prot4081

Category: DNA Protocols: cDNA Library Protocols: cDNA Library Construction Protocols

Shotgun sequencing of a large segment of DNA involves random fragmentation of the target region into smaller segments that are subsequently cloned into a bacteriophage M13 vector. The goal is to create a library of overlapping clones that provide at least fivefold coverage over the entire length of the target fragment. - [Read Generation of a Library of Randomly Overlapping DNA Inserts Protocol]
