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...

Next-generation Sequencing

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

Maxam-Gilbert Sequencing

Maxam-Gilbert Sequencing

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Sanger Sequencing

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

DNA Agarose Gel Electrophoresis

DNA Agarose Gel Electrophoresis

Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...

Background:

Recent advances in understanding DNA interactions have spurred the development of DNA-based self-assembled structures.
DNA-DNA interactions are crucial for the properties and assembly of these novel materials.
Exploiting programmable selectivity and tunable interaction strength of DNA is key to designing complex structures.

Purpose of the Study:

To review the state-of-the-art in molecular and colloidal systems interacting via DNA.
To discuss both fully DNA-constructed systems and hybrid systems incorporating colloidal particles.
To focus on systems where DNA-mediated interactions lead to emergent "phases" at large length scales.

Main Methods:

Review of existing literature on DNA-mediated self-assembly.
Analysis of systems involving DNA-coated colloidal particles (e.g., latex, metal).
Focus on self-assembly driven by DNA interactions, leading to phase formation.

Main Results:

DNA-mediated interactions enable the creation of diverse self-assembled structures.
Systems exhibit hierarchical structuring and phase formation over large length scales.
Tunable DNA interactions allow for a wide range of self-assembly patterns, including amorphous, liquid crystalline, and crystalline phases in 1D, 2D, and 3D.

Conclusions:

DNA-mediated self-assembly is a rapidly emerging field with significant potential in materials science and nanotechnology.
