This design is very different from that of Sanger sequencing—also known as capillary sequencing or first-generation sequencing—which is based on electrophoretic separation of chain-termination products produced in individual sequencing reactions. [6] This methodology allows sequencing to be completed on a larger scale. [7]
These types of false-positive variants are filtered out by the duplex sequencing method since mutations need to be accurately matched in both strands of DNA to be validated as true mutations. Duplex sequencing can theoretically detect mutations with frequencies as low as 10 −8 compared to the 10 −2 rate of standard NGS methods. [1] [2] [10]
[23] [46] [49] In the most common protocols for genome-wide knockouts, a 'Next-generation sequencing (NGS) library' is created by a two step polymerase chain reaction (PCR). [23] [46] The first step amplifies the sgRNA region, using primers specific to the lentiviral integration sequence, and the second step adds Illumina i5 and i7 sequences. [23]
SNV calling from NGS data is any of a range of methods for identifying the existence of single nucleotide variants (SNVs) from the results of next generation sequencing (NGS) experiments. These are computational techniques, and are in contrast to special experimental methods based on known population-wide single nucleotide polymorphisms (see ...

One type of sequencing method can be used in preference to another depending on the type of the sample, for a genomic sample assembly-based methods is used; for a metagenomic sample it is preferable to use read-based methods. [10] Metagenomic sequencing methods have provided better results than genomics, due to these present fewer false negatives.
During sequencing, each base in the template is sequenced twice, and the resulting data are decoded according to this scheme. SOLiD (Sequencing by Oligonucleotide Ligation and Detection) is a next-generation DNA sequencing technology developed by Life Technologies and has been commercially available since
The degree of multiplexing is constrained by the multiplexing capability of the method chosen for target identification. If array-based detection methods are used, the number of targets that can be assayed is limited by the available spots on the array. Since a distinct probe is needed to capture each region, it is costly to assay many regions ...
