DNA Isolation

DNA Isolation

DNA from cells is required for many biotechnology and research applications, such as molecular cloning. To remove and purify DNA from cells, researchers use various methods of DNA extraction. While the specifics of different protocols may vary, some general concepts underlie the process of DNA extraction.

DNA Isolation

DNA Isolation

DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

Genomic DNA in Eukaryotes

Genomic DNA in Eukaryotes

Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Background:

Duplex sequencing offers enhanced accuracy by linking complementary DNA strands.
Concatenating Original Duplex for Error Correction (CODEC) is a cost-effective duplex sequencing method.
Widespread adoption of CODEC is hindered by a lack of detailed wet-lab protocols.

Purpose of the Study:

To provide a detailed, experimentally validated protocol for CODEC library preparation.
To ensure compatibility with standard Illumina sequencing platforms.
To facilitate reproducible implementation of CODEC for research applications.

Main Methods:

The protocol includes blunt-end fragmentation, dideoxy base-blocked A-tailing, and CODEC adapter ligation.
Strand-displacing extension and library amplification are incorporated.
Quality control checkpoints, critical parameters, and troubleshooting guidance are provided.

Main Results:

An experimentally validated protocol for CODEC library preparation from genomic DNA is described.
The protocol is compatible with standard Illumina sequencing platforms.
An optional matched germline reference library preparation protocol is included.

Conclusions:

This workflow enables reproducible CODEC library preparation in molecular biology labs.
It supports accurate detection of low-frequency somatic variants.
The protocol aims to broaden the adoption of cost-effective duplex sequencing.
