History of DNA sequencing “DNA sequencing method developed by Fred Sanger “ In the 1980s, two key developments allowed researchers to believe that sequencing the entire genome could be possible. Next-generation sequencing involves three basic steps: library preparation, sequencing, and data analysis. Instead of one tube per reaction, a complex library of DNA templates is densely immobilized onto a two-dimensional surface, with all templates accessible to a single reagent volume. After first being developed by Frederick Sanger and colleagues in 1977, it became the most widely used sequencing method for approximately 40 years. The information provided assumes you want to sequence a PCR product, a plasmid, a BAC, a phage lambda or a cosmid.

Furthermore, Sanger sequencing is analogical while next-generation sequencing is digital, allowing the detection of the novel or rare … The main difference between Sanger sequencing and next-generation sequencing is that Sanger sequencing processes only a single DNA fragment at a time, whereas next-generation sequencing processes millions of fragments simultaneously at a time. The first DNA sequence was obtained by academic researchers, using laboratories methods based on 2- dimensional chromatography in the early 1970s. 2.1 Sanger Sequencing. From Sanger to Next-Generation Sequencing in Neurogenetics Introduction The worldwide success of next-generation sequencing (NGS) in research and clinical laboratories, the advent of affordable bench- top NGS machines and an increased knowledge on the genetics of disease, have revolutionized the molecular diagnosis field.
