Primer Premier
Primer Premier software combines design of primers for various PCR applications under one common platform. The software supports design of degenerate primers on alignments for amplifying a related set of nucleotide sequences for detecting many common traits amongst organisms and to determine heredity. The software also designs tagged and nested primers for multiplex PCR reactions. The Primer Premier software supports motif analysis and ORF search along with finding restriction cut sites on the nucleotide sequence. The software has a built-in nucleotide-protein and protein-nucleotide sequence translator which can be used for designing degenerate primers for codons that code for multiple amino acid sequences. It is also understood that the primers designed by Primer Premier are effective and confirm to the design guidelines laid for designing primers for housekeeping genes with a high G+C%. The software also designs primers for flanking exons and introns in a gene, though there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bioinformatics
Bioinformatics () is an interdisciplinary field that develops methods and software tools for understanding biological data, in particular when the data sets are large and complex. As an interdisciplinary field of science, bioinformatics combines biology, chemistry, physics, computer science, information engineering, mathematics and statistics to analyze and interpret the biological data. Bioinformatics has been used for '' in silico'' analyses of biological queries using computational and statistical techniques. Bioinformatics includes biological studies that use computer programming as part of their methodology, as well as specific analysis "pipelines" that are repeatedly used, particularly in the field of genomics. Common uses of bioinformatics include the identification of candidates genes and single nucleotide polymorphisms (SNPs). Often, such identification is made with the aim to better understand the genetic basis of disease, unique adaptations, desirable properties (e ...

Applications Of PCR
The polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies (complete or partial) of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it (or a part of it) to a large enough amount to study in detail. PCR was invented in 1983 by the American biochemist Kary Mullis at Cetus Corporation; Mullis and biochemist Michael Smith, who had developed other essential ways of manipulating DNA, were jointly awarded the Nobel Prize in Chemistry in 1993. PCR is fundamental to many of the procedures used in genetic testing and research, including analysis of ancient samples of DNA and identification of infectious agents. Using PCR, copies of very small amounts of DNA sequences are exponentially amplified in a series of cycles of temperature changes. PCR is now a common and often indispensable technique used in medical laboratory research for a broad variety of applications including biomedical research and ...

Multiplex PCR
Multiplex polymerase chain reaction (Multiplex PCR) refers to the use of polymerase chain reaction to amplify several different DNA sequences simultaneously (as if performing many separate PCR reactions all together in one reaction). This process amplifies DNA in samples using multiple primers and a temperature-mediated DNA polymerase in a thermal cycler. The primer design for all primers pairs has to be optimized so that all primer pairs can work at the same annealing temperature during PCR. Multiplex-PCR was first described in 1988 as a method to detect deletions in the dystrophin gene. It has also been used with the steroid sulfatase gene. In 2008, multiplex-PCR was used for analysis of microsatellites and SNPs. In 2020, RT-PCR multiplex assays were designed that combined multiple gene targets from the Center for Diseases and Control in a single reaction to increase molecular testing accessibility and throughput for SARS-CoV-2 diagnostics. Multiplex-PCR consists of multi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNASTAR
DNASTAR is a global bioinformatics software company incorporated in 1984 that is headquartered in Madison, Wisconsin. DNASTAR develops and sells software for sequence analysis in the fields of genomics, molecular biology, and structural biology. Software DNASTAR software (Lasergene) first gained popularity in the 1980s and 1990s for its sequence assembly and analysis capabilities of Sanger sequencing data. Lasergene 17.3.3 was released in June 2022. DNASTAR software is available for desktop computers running Mac OS X, Windows, and Linux as well as for use on Amazon Web Services. In 2007, DNASTAR expanded their offerings to include software for next-generation sequencing and structural biology. DNASTAR's next-gen software supports data from Illumina, Ion Torrent, and Pacific Biosciences and allows the user to assemble, align, analyze and visualize genomic data. Lasergene's use in next-generation sequence assembly and analysis was contributed as a chapter, written by company sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AlleleID
AlleleID designs oligos for strain differentiation and taxa specific assays. This aids in bacterial identification, pathogen detection and species identification. The software is designed to run on Windows and Macintosh operating system. AlleleID aligns sequences to locate differences in DNA and to find conserved regions and then designs oligos to amplify and detect only the species or strains of interest from the mix. The platforms for which AlleleID includes support are: # Quantitative PCR: Designs species specific and taxa specific qPCR assays # Microarrays: Designs species specific and taxa specific microarrays # xMAP: Designs oligos for Direct Hybridization Assays (DHA) and ASPE assays # MLPA: Designs probes for copy number detection and SNP studies References {{reflist External linksAlleleID Homepage [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Site-directed Mutagenesis
Site-directed mutagenesis is a molecular biology method that is used to make specific and intentional mutating changes to the DNA sequence of a gene and any gene products. Also called site-specific mutagenesis or oligonucleotide-directed mutagenesis, it is used for investigating the structure and biological activity of DNA, RNA, and protein molecules, and for protein engineering. Site-directed mutagenesis is one of the most important laboratory techniques for creating DNA libraries by introducing mutations into DNA sequences. There are numerous methods for achieving site-directed mutagenesis, but with decreasing costs of oligonucleotide synthesis, artificial gene synthesis is now occasionally used as an alternative to site-directed mutagenesis. Since 2013, the development of the CRISPR/Cas9 technology, based on a prokaryotic viral defense system, has also allowed for the editing of the genome, and mutagenesis may be performed ''in vivo'' with relative ease.
