PCR fragmentation of DNA.

A method has been developed to prepare random DNA fragments using PCR. First, two cycles are carried out at 16 degrees C with the Klenow's fragment and oligonucleotides (random primers) with random 3'-sequences and the 5'-constant part containing the site for cloning with the site-specific endonuclease. The random primers can link to any DNA site, and random DNA fragments are formed during DNA ...

Measuring of DNA Damage by Quantitative PCR

PCR is an in vitro method of nucleic acid synthesis by which a particular segment of DNA can be specifically replicated. It involves two oligonucleotide primer that flank the DNA fragment to be amplified and repeated cycles of heat denaturation of the DNA, annealing of the primers to their complementary sequences, and extension of the annealed primers with DNA polymerase. Successive cycles of a...

Apoptotic nuclear morphological change without DNA fragmentation

Apoptosis is characterized morphologically by condensation and fragmentation of nuclei and cells and biochemically by fragmentation of chromosomal DNA into nucleosomal units [1]. CAD, also known as CPAN or DFF-40, is a DNase that can be activated by caspases [2] [3] [4] [5] [6]. CAD is complexed with its inhibitor, ICAD, in growing, non-apoptotic cells [2] [7]. Caspases that are activated by ap...

Development of a Sensitive Quantitative Competitive PCR Assay for Detection of Human Cytomegalovirus DNA

Accurate and rapid diagnosis of human cytomegalovirus (HCMV) disease in immunocompromised patients has remained as a challenge. Quantitative competitive PCR (QC-PCR) methods for detection of HCMV in these individuals have improved the positive and negative predictive values of PCR for diagnosis of HCMV disease. In this study we used QC-PCR assay, using a co-amplified DNA standard, to quantitate...

Autophosphorylation-dependent remodeling of the DNA-dependent protein kinase catalytic subunit regulates ligation of DNA ends.

Non-homologous end joining (NHEJ) is one of the primary pathways for the repair of ionizing radiation (IR)-induced DNA double-strand breaks (DSBs) in mammalian cells. Proteins required for NHEJ include the catalytic subunit of the DNA-dependent protein kinase (DNA-PKcs), Ku, XRCC4 and DNA ligase IV. Current models predict that DNA-PKcs, Ku, XRCC4 and DNA ligase IV assemble at DSBs and that the ...
