The first automated DNA sequencer, invented by Lloyd M. Smith, was introduced by Applied Biosystems in 1987. [1] It used the Sanger sequencing method, a technology which formed the basis of the "first generation" of DNA sequencers [2] [3] and enabled the completion of the human genome project in 2001. [4]
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ...
Automated DNA-sequencing instruments (DNA sequencers) can sequence up to 384 DNA samples in a single batch. Batch runs may occur up to 24 times a day. DNA sequencers separate strands by size (or length) using capillary electrophoresis, they detect and record dye fluorescence, and output data as fluorescent peak trace chromatograms.
The company shipped the first gas phase protein sequencer, Model 4790A, in August 1982. The 380 DNA synthesizer was commercialized in 1983, the 430A peptide synthesizer in 1984, and the 370A DNA sequencing system in 1986. [56] [5] These new instruments had a major impact on the emerging fields of proteomics and genomics.
The two sequencer and synthesizer products allowed molecular biologists to clone genes by building oligonucleotides with the desired protein's DNA sequence. [1] Automated DNA sequencing began at the California Institute of Technology, using fluorescent dyes, with Rights to the technology granted to Applied Biosystems. [1] At CIT, Dr. Leroy Hood ...
In 1982, Smith did post-doctorate work with Leroy Hood at the California Institute of Technology, where he created the world's first fluorescence-based automated DNA sequencing instrument. [ 2 ] [ 4 ] [ 5 ] During the early 80s he also worked as a consultant for Applied Biosystems , who were able to commercialise the sequencing process he ...
Frederick Sanger OM CH CBE FRS FAA (/ ˈ s æ ŋ ər /; 13 August 1918 – 19 November 2013) was a British biochemist who received the Nobel Prize in Chemistry twice.. He won the 1958 Chemistry Prize for determining the amino acid sequence of insulin and numerous other proteins, demonstrating in the process that each had a unique, definite structure; this was a foundational discovery for the ...
Whole genome sequencing (WGS) is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a single time. [2] This entails sequencing all of an organism's chromosomal DNA as well as DNA contained in the mitochondria and, for plants, in the chloroplast.
