Pyrosequencing is a method of DNA sequencing (determining the order of nucleotides in DNA) based on the "sequencing by synthesis" principle, in which the sequencing is performed by detecting the nucleotide incorporated by a DNA polymerase. Pyrosequencing relies on light detection based on a chain reaction when pyrophosphate is released. Hence ...
Pyrosequencing has also been used to analyze bisulfite-treated DNA without using methylation-specific PCR. [7] [8] Following PCR amplification of the region of interest, pyrosequencing is used to determine the bisulfite-converted sequence of specific CpG sites in the region. The ratio of C-to-T at individual sites can be determined ...
This technique uses sequence-specific termination of a DNA synthesis reaction using modified nucleotide substrates. However, new sequencing technologies such as pyrosequencing are gaining an increasing share of the sequencing market. More genome data are now being produced by pyrosequencing than Sanger DNA sequencing.
Pyrosequencing uses luciferase to generate light for detection of the individual nucleotides added to the nascent DNA, and the combined data are used to generate sequence reads. [81] This technology provides intermediate read length and price per base compared to Sanger sequencing on one end and Solexa and SOLiD on the other.

What Is Today's Strands Hint for the Theme: "What's Your Reaction?"? Today's Strands game revolves around things that can trigger an immune response (making you feel bad in the process).
It was developed by 454 Life Sciences and purchased by Roche in 2007. 454 utilizes the detection of pyrophosphate released by the DNA polymerase reaction when adding a nucleotide to the template strain. Roche currently manufactures two systems based on their pyrosequencing technology: the GS FLX+ and the GS Junior System. [11]
White explained in an email that his reaction to Hazelden’s plan was “one of pleasant surprise that a leading addiction treatment program would so value the emerging addiction science and be so committed to improving recovery outcomes that it would be willing to weather potential controversy that could affect its business interests.”
