MIT automates quantitative analysis of DNA comets

May 05 2010

DNA comets - where healthy and damaged DNA is separated through electrophoresis - have posed a quantitative analysis challenge for three decades.

Comet assaying uses electrophoresis to spread DNA into a comet-like formation on the surface of a gel substrate.

The process works due to the surface charge of particles, which causes them to move differently when an external electric field is applied.

Damaged DNA typically moves further than healthy DNA, creating a formation similar to a comet's tail.

However, there has previously been no way to automate the quantitative analysis of the results, making for a time- and labour-consuming process.

Now, Massachusetts Institute of Technology (MIT) scientists have created a microscopic patterning grid for the resultant comet, allowing individual areas to be labelled.

In turn, this allows for the process of analysis to be automated, removing the labour from the procedure and accelerating the time taken to achieve a result.

"The technology could offer a new approach for epidemiologists to detect dangerous environmental exposures long before they cause cancer," the researchers claim.
