Finisher may refer to In the field of genome sequencing , a finisher is one who analyzes an electropherogram , a graphical representation of data received from a sequencing machine and yields one read, in comparison to the consensus, a sequence that has been generated from the alignment of multiple reads, presented by the computer program s Phred quality score Phred and Phrap , to determine if the consensus accurately reflects the nucleotide sequence when the data is incomplete or inadequate, the finisher calls more reactions with appropriate chemistry in order to gather more data. In computing, a printer computing printer finisher performs post printing actions, such as stapling, hole punching, folding, or collating. In cricket , the term finisher can also refer to the name given to the role played by a Not out not out batsman that results in his her team winning the match.

Cleanup date April 2008 Microsatellite genetics Microsatellites are repeated sequences of DNA. Although the length of these microsatellites is highly variable from person to person, each individual has microsatellites of a set length. These repeated sequences are common, and normal. The most common microsatellite in humans is a dinucleotide repeat of CA, which occurs tens of thousands of times across the genome. Image Microsatellite Instability in GeneMarker.jpg thumb 400px Example of Microsatellite Instability in a DNA Electropherogram Trace In cells with mutations in DNA repair genes, however, some of these sequences accumulate errors and become longer or shorter. The appearance of abnormally long or short microsatellites in an individual s DNA is referred to as microsatellite instability. Microsatellite instability MSI is a condition manifested by damaged DNA due to defects in the normal DNA repair process. ref MeshName Microsatellite Instability ref Sections of DNA called Microsatellite genetics microsatellite s, which consist of a DNA sequence sequence of repeating units of 1 6 base pair s in length, become unstable and can shorten or lengthen. Microsatellites are also known as simple sequence repeats SSRs . Clinical significance MSI is a key factor in several cancers including colorectal, endometrial, ovarian and gastric cancers. Colorectal cancer studies have demonstrated two mechanisms for MSI occurrence. The first is in hereditary nonpolyposis colorectal cancer HNPCC or Lynch Syndrome, where an inherited mutation in a mismatch repair gene causes a microsatellite repeat replication error to go unfixed. Most cases result in changes in the lengths of dinucleotide repeats of the nucleobase s cytosine and adenine sequence CACACACACA... . ref cite pmid 10321739 ref The replication error results in a frameshift mutation that inactivates or alters major tumor suppressor genes key genes in the regulation of the cell cycle and, ultimately, the prevention of cancer.

Orphan date April 2012 Label free HPCE High Performance Capillary Electrophoresis is used in the life science industries for the analysis of biomolecules, principally in the detection and quantification of protein , DNA and RNA . Process Label free HPCE systems utilise Label free intrinsic imaging technology LFII and the data analysis of DNA and proteins in such systems are enabled by Generalized Separation Transform GST and Equiphase Vertexing EV algorithms. ref http www.selectscience.net application notes deltadot analysis of immunoglobulin g igg using deltadots peregrine high performance capillary electrophoresis hpce with label free intrinsic imaging lfii ?artID 13016 ref LFII eliminates the need for labels commonly required in capillary electrophoresis CE systems. GST is a method of combining the data from multiple pixel diode arrays in a way that preserves the peak shape information of the electropherograms. EV is a technique that uses a space time constraint to significantly increase the signal to noise ratio , to improve Sensor resolution resolution and to allow associations of a given band in the electrophoretic window with a given injection. In EV the electropherogram s are first analyzed to find local peaks that are then used to determine the origin of the bands through vertexing and then to produce a significantly enhanced signal output. Advantages Multipoint detection and label free photonic imaging have mathematical and physicochemical consequences that provide important advantages. First the geometric method of analysis makes it possible to use powerful signal processing algorithms that are computationally highly efficient and can run in real time on a standard PC. Secondly, the ability to use powerful signal processing algorithms allows the use of very low signal levels which permits the use of photonic imaging rather than label detection. Thirdly, photonic imaging has the advantage over the use of labels that the strength of the signal depends on th ... more details

Image Electropherogram trace.jpg thumb 300px Example of AFLP Data from a Capillary Electrophoresis Instrument AFLP PCR or just AFLP is a polymerase chain reaction PCR based tool used in genetics research, DNA fingerprint ing, and in the practice of genetic engineering . Developed in the early 1990s by Keygene, ref http www.keygene.com ref AFLP uses restriction enzymes to digest Genome genomic DNA , followed by ligation of adaptors to the sticky ends of the restriction fragment s. A subset of the restriction fragments is then selected to be amplified. This selection is achieved by using primers complementary to the adaptor sequence, the restriction site sequence and a few nucleotides inside the restriction site fragments as described in detail below . The amplified fragments are visualized on denaturing polyacrylamide electrophoresis gels either through autoradiography or fluorescence methodologies. AFLP is not an acronym and, despite hundreds of publications that do so, it is incorrect to refer to AFLP as Amplified fragment length polymorphism , ref cite journal author Vos P, Hogers R, Bleeker M, et al. title AFLP a new technique for DNA fingerprinting journal Nucleic Acids Res. volume 23 issue 21 pages 4407 14 year 1995 month November pmid 7501463 pmc 307397 url http nar.oxfordjournals.org cgi pmidlookup?view long&pmid 7501463 doi 10.1093 nar 23.21.4407 ref as the resulting data are not scored as length polymorphisms, but instead as presence absence polymorphisms.
