How Does Illumina Sequencing Work. DNA sequencing, which determines the order of nucleotides in a DNA strand, allows scientists to read the genetic code so they can study the normal versions of genes. Within a gene, the amino acids provide instructions that can be read by special substances in the body to determine what type of protein needs to be made. Hence, the method is also called Solexa/Illumina sequencing method. The ability to read the sequence of DNA code has revolutionized biology in recent decades. Common DNA Sequencing Methods. O After PCR, the replicated DNA strands are split into four pools. The ‘HiSeq’ produces the highest yields (up to 75 billion bases, or Gb) per sample with maximum read length of 100 bases from both ends of each template. How does a Illumina DNA sequencer determine the sequence of a DNA strand? Illumina Sequencing Overview. Illumina, the dominant maker of DNA sequencers that are used in drug discovery, medicine, and biological research, is unveiling a new toy: A $19,900, one-cubic-foot box that puts DNA sequencing … The order of all these DNA letters is called your genome sequence. It has led to massive insights in the understanding of biology and disease. Special codes signal when the DNA letters are part of a gene. Each pool goes through elongation with all four regular deoxynucleotides and fluorescent dideoxynucleotides of one kind, creating various length of DNA chains that terminate with the fluorescent dideoxynucleotide. Illumina currently sells several versions of its DNA sequencing machine, all of which use essentially the same sample prep kits and sequencing technology. Whole-Genome Sequencing. 2 Illumina sequencing systems can deliver data output ranging from 300 kilobases up to multiple terabases in a single run, depending on instrument type and configuration. The Illumina Long-Read Applications Ecosystem is a group of partnerships dedicated to ensuring the delivery of high-quality data for a fully featured genome, including phasing, detection of structural variants, and de novo assembly of all species. Compare Sequencers. It also allows them to make comparisons between normal versions of a gene and disease-causing versions of a gene. The Galleri test uses Illumina sequencers to detect tumor-associated DNA modifications. Then Illumina purchased Solexa in 2007, rapidly improving the original technology. Three letter combinations of DNA refer to specific amino acids. The main advantage of Illumina sequencing is that it delivers a high yield of error-free reads. As scientists have improved on sequencing techniques, it has become even cheaper and easier to read DNA sequences. Compare the speed and throughput of Illumina DNA sequencing systems to find the best option for your lab.
