Sanger sequencing of the S-gene provides a quick, accurate, and more affordable method to retrieving the genetic code. Laboratories in lower income countries may not have the capabilities to implement expensive applications such as next generation sequencing, so Sanger methods may prevail in supporting the generation of sequencing data for ...
SOLiD applies sequencing by ligation and dual base encoding. The first SOLiD system was launched in 2007, generating reading lengths of 35bp and 3G data per run. After five upgrades, the 5500xl sequencing system was released in 2010, considerably increasing read length to 85bp, improving accuracy up to 99.99% and producing 30G per 7-day run. [10]
This technique offers several advantages over traditional sequencing methods such as Sanger sequencing. Sanger sequencing requires two reactions, one for the forward primer and another for the reverse primer. Unlike Illumina, Sanger sequencing uses fluorescently labeled dideoxynucleoside triphosphates (ddNTPs) to determine the sequence of the ...
DNA sequencing is the process of determining the nucleotide order of a given DNA fragment. So far, most DNA sequencing has been performed using the chain termination method developed by Frederick Sanger. This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates.
In contrast to directed sequencing, shotgun sequencing of DNA is a more rapid sequencing strategy. [6] There is a technique from the "old time" of genome sequencing. The underlying method for sequencing is the Sanger chain termination method which can have read lengths between 100 and 1000 basepairs (depending on the instruments used).

Coulson joined Sanger's group at the Medical Research Council’s Laboratory of Molecular Biology (LMB) as a technician in 1967, shortly after receiving his diploma. [1] [3] With Sanger, Coulson developed many of the early DNA sequencing technologies, [3] [4] including the DNA polymerase primed synthesis ("plus and minus") technique [5] and, eventually, dideoxynucleotide chain-terminating ...
