A study in 2016 presented a novel method called hybridization RAD (hyRAD), [12] where biotinylated RAD fragments, covering a random fraction of the genome, are used as baits for capturing homologous fragments from genomic shotgun sequencing libraries. DNA fragments are first generated using ddRADseq protocol applied to fresh samples, and used ...
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.

Amplified fragment length polymorphism (AFLP-PCR or AFLP) is a PCR-based tool used in genetics research, DNA fingerprinting, and in the practice of genetic engineering. Developed in the early 1990s by Pieter Vos, [1] AFLP uses restriction enzymes to digest genomic DNA, followed by ligation of adaptors to the sticky ends of the restriction ...
Restriction digest is most commonly used as part of the process of the molecular cloning of DNA fragment into a vector (such as a cloning vector or an expression vector).The vector typically contains a multiple cloning site where many restriction site may be found, and a foreign piece of DNA may be inserted into the vector by first cutting the restriction sites in the vector as well the DNA ...
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.
For example, the standard protocols for DNA fingerprinting involve PCR analysis of panels of more than a dozen VNTRs. RFLP is still used in marker-assisted selection. Terminal restriction fragment length polymorphism (TRFLP or sometimes T-RFLP) is a technique initially developed for characterizing bacterial communities in mixed-species samples.
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.
Circulating tumour DNA (ctDNA) molecules are tumour-derived cell-free DNA (cfDNA) circulating in the bloodstream and are not associated with cells. CtDNA primarily arises from chromatin fragmentation accompanying tumour cell death [12] and can be extracted by liquid biopsy. [13]
