DNA sequencing - the Illumina method
Watch or download our animation on Illumina, sequencing DNA around 20 times cheaper than the 454 technology - $0.001 per 1000 bases - and taking just half a day to read one gigabase. They also have the advantage of being able to run more samples simultaneously.
In this method, single DNA fragments are amplified in dense clusters on a hollow slide to provide strong fluorescence signals.
