Illumina sequencing machines in the sequencing centre at the Sanger Institute in 2009. Millions of reactions and the reversible terminators The Solexa/Illumina sequencing method is similar to Sanger sequencing, but it uses modified dNTPs containing a terminator which blocks further polymerization- so only a single base can be added by a polymerase enzyme to each growing DNA copy strand. In the Illumina sequencing workflow, these adapters contain complementary sequences that allow the DNA fragments to bind to the flow cell. The double-stranded DNA is then broken down into single-stranded DNA using heat, leaving several million dense clusters of identical DNA sequences. The most popular of these shotgun methods was probably Solexa, which saw DNA broken up and adhered to a glass … Short sequences of DNA called adaptors?, are attached to the DNA fragments. The AmpliSeq protocol recommends partially digest primer sequences after targeted amplification. Since Illumina sequencing gives sequence reads with high accuracy, it is the widely-used sequencing method in the world. In automated Sanger sequencing, a computer reads each band of the capillary gel, in order, using fluorescence to call the identity of each terminal ddNTP. how does illumina sequencing work. The process begins with a sample of double-stranded DNA. Illumina (Solexa) sequencing: Illumina sequencing works by simultaneously identifying DNA bases, as each base emits a unique fluorescent signal, and adding them to a nucleic acid chain Roche 454 sequencing: This method is based on pyrosequencing, a technique which detects pyrophosphate release, again using fluorescence, after nucleotides are incorporated by polymerase to a new strand of DNA. • Massively Parallel Sequencing – “Next-Generation Sequencing” (NGS) • Does not use Sanger method • Different Platforms = Different Chemistries • Very High throughput instruments – >100 gigabases of DNA sequence/day • Desktop Sized Sequencing Instruments & Beyond!

After the addition of each complementary nucleotide, the clusters in the flow cell are observed for the emission of fluorescence. When the sequencing reaction is performed in the presence of all four terminated nucleotides, you eventually get a pool of DNA fragments that are measured and separated base by base. Next Generation Sequencing, will give you a plethora of reads, but they will be short. The length of these sections will depend on the particular sequencing machinery used. The four steps involved in Illumina sequencing are described below. Then the terminator group of the 3′ position of the sugar is regenerated by a hydroxyl group, allowing the addition of a second dNTP to the growing chain. The completion of the Human Genome Project in 2003 ushered in a new era of rapid, affordable, and accurate genome analysis—called Next Generation Sequencing (NGS). The Illumina sequencing technology, including technical aspects and biochemistry, has been described previously (Bentley et al., 2008).It has been shown that the number of positive target sites identified by ChIP-seq in general increases with the amount of sequencing reads (Myers et al., 2011). After taking a look on the Internet I found an explanation of what is paired-end sequencing (tell me if I got it right): For what I understood, a paired-end sequencing is just done by sequencing from A to Z and then from Z to A. Tn5 simultaneously fragments DNA, preferentially inserts into open chromatin sites, and adds sequencing primers (a process known as tagmentation). The DNA polymerase then continues synthesis until it adds a different ddNTP. Illumina sequencing generates many millions of highly accurate reads making it much faster and cheaper than other available sequencing methods.
