Although the read length is much shorter than Roche-454 and PacBio, due to lower costs, Ion Torrent can be a reasonable choice in some cases. Although Ion Proton is capable of generating much larger outputs (around 10 GB), it is substantially more expensive.ДЄdvantages: Ion Torrent generates read lengths of around 200 bp, which are used to fill gaps in the assembly produced by other technologies. It uses larger chips with higher densities, and thus can be suitable for exome and whole-genome sequencing. However, in September 2012, Ion Torrent launched their bigger system, the Ion Proton. Ion torrent PGM (Personal Genome Machine) generates a total data output of around 10вЂ“1,000 MB, depending upon the type of ion semiconductor sequencing chip used. This process is repeated 20 times or more creating a multi-layer system of circuits. The transistors and circuits are then pattern-transferred and subsequently etched onto the wafers using photolithography.

These are cut in the form of wafers from a silicon boule. These ion semiconductor chips are designed and manufactured like any other semiconductor chips used in electronic devices. Hydrogen ions are detected on ion-semiconductor sequencing chips. Instead of detecting light as in 454 pyrosequencing, Ion Torrent technology creates a direct connection between the chemical and digital events. If there are two identical bases on the DNA strand, the output voltage is doubled, and the chip records two identical bases called without scanning, camera, and light. The ion changes the pH of the solution, which is detected by an ion sensor. Beneath the wells is an ion-sensitive layer followed by a proprietary ion-sensor. Each well holds a different DNA template. Ion Torrent, with its Ion Personal Genome Machine (PGMв„ў) sequencer, uses a high-density array of micro-machined wells to perform nucleotide incorporation in a massively parallel manner. In nature, when a nucleotide is incorporated into a strand of DNA by a polymerase, a hydrogen ion is released as a by-product. Ion Torrent: Ion Torrent technology works on the principle of detection of hydrogen ion release during incorporation of new nucleotides into the growing DNA template.

In January of 2012, Life Technologies officially launched its second semiconductor platform, the Ion Torrent Protonв„ў sequencer, which uses a novel complementary metal-oxide semiconductor (CMOS) chip with 165 million 1.3В mm-diameter microwells, automatically templated submicron particles, and integrated hardware and software that enable acquisition of about 5 billion data points per second over a 2вЂ“4В h run time with on-instrument signal processing. It is therefore ideal for smaller laboratories that wish to use NGS in their work but do not require extremely large data sets. Mass production of the Ion Chip achieved by using standard semiconductor techniques and reaction volume miniaturization make this technology relatively inexpensive and fast. The average read length obtained on the PGM has increased from 100 to 200В bp over the last several years. The Ion Chip has an upper surface that serves as a microfluidic conduit to deliver the reagents needed for the sequencing reactions as well as a lower surface which interfaces directly with a hydrogen ion detector that translates the released hydrogen ions from each well into a quantitative readout of nucleotide bases. Enriched particles are primed for sequencing by annealing a sequencing primer and are then loaded into the wells of an Ion Chip. The ISPs have covalently linked complementary adapter sequences on their surfaces to facilitate amplification on the particles. Template preparation is carried out using an emPCR and enrichment system on Ion Spheresв„ў Particles (ISPs).

Sequence template preparation can be performed manually or by use of a OneTouchв„ў Machine (Life Technologies). Ion Torrent library construction includes DNA fragmentation, partial digestion of primer sequences, ligation of adapters, and library purification. Used with permission from Life Technologies.
