  1. Nested polymerase chain reaction

    Image Nested PCR.png thumb 250px A diagram illustrating the method of nested PCR. Nested polymerase chain reaction is a modification of polymerase chain reaction intended to reduce the contamination in products due to the amplification of unexpected primer binding sites. Polymerase chain reaction itself is the process used to amplify DNA samples, via a temperature mediated DNA polymerase . The products can be used for sequencing or analysis, and this process is a key part of many genetics research laboratories, along with uses in DNA fingerprinting for forensics and other human genetic cases. Conventional PCR requires primer molecular biology primers complementary to the termini of the target DNA. A commonly occurring problem is primers binding to incorrect regions of the DNA, giving unexpected products. Nested polymerase chain reaction involves two sets of primers, used in two successive runs of polymerase chain reaction, the second set intended to amplify a secondary target within the first run product. Processes The target DNA undergoes the first run of polymerase chain reaction with the first set of primers, shown in green. The selection of alternative and similar primer binding sites gives a selection of products, only one containing the intended sequence. The product from the first reaction undergoes a second run with the second set of primers, shown in red. It is very unlikely that any of the unwanted PCR products contain binding sites for both the new primers, ensuring the product from the second PCR has little contamination from unwanted products of primer dimers, hairpins ...

  1. Touchdown polymerase chain reaction

    Touchdown polymerase chain reaction or touchdown style polymerase chain reaction is a method of polymerase chain reaction by which primer molecular biology primers will avoid amplifying nonspecific sequences. The Annealing biology annealing temperature during a polymerase chain reaction determines the specificity of primer annealing. The Denaturation biochemistry melting point of the primer sets the upper limit on annealing temperature. At temperatures just below this point, only very specific base pairing between the primer and the template will occur. At lower temperatures, the primers bind less specifically. Nonspecific primer binding obscures polymerase chain reaction results, as the nonspecific sequences to which primers anneal in early steps of amplification will swamp out any specific sequences because of the exponential growth exponential nature of polymerase amplification. The earliest steps of a touchdown polymerase chain reaction cycle have high annealing temperatures. The annealing temperature is decreased in increments for every subsequent set of cycles the number of individual cycles and increments of temperature decrease is chosen by the experimenter . The primer will anneal at the highest temperature which is least permissive of nonspecific binding that it is able to tolerate. Thus, the first sequence amplified is the one between the regions of greatest primer specificity it is most likely that this is the sequence of interest. These fragments will be further amplified during subsequent rounds at lower temperatures, and will out compete the nonspecific sequences to which the primers may bind at those lower temperatures. If the primer initially during the higher temperature phases binds to the sequence of interest, subsequent rounds of polymerase chain reaction can be performed upon the product to further amplify those fragments.

  1. Digital polymerase chain reaction

    Digital Polymerase Chain Reaction digital PCR, DigitalPCR, dPCR, or dePCR is a refinement of conventional polymerase chain reaction methods that can be used to directly quantify and clonally amplify nucleic acids including DNA , cDNA or RNA . The key difference between dPCR and traditional PCR lies in the method of measuring nucleic acids amounts, with the former being a more precise method than PCR. PCR carries out one reaction per single sample. dPCR also carries out a single reaction within a sample, however the sample is separated into a large number of partitions and the reaction is carried out in each partition individually. This separation allows a more reliable collection and sensitive measurement of nucleic acid amounts. The method has been demonstrated as useful for studying variations in gene sequences such as copy number variants and point mutations and it is routinely used for clonal amplification of samples for next generation sequencing . PCR Basics The polymerase chain reaction method is used to quantify nucleic acids by amplifying a nucleic acid molecule with the enzyme DNA polymerase . Conventional PCR is based on the theory that amplification is exponential. Therefore, nucleic acids may be quantified by comparing the number of amplification cycles and amount of PCR end product to those of a reference sample. However, many factors complicate this calculation, creating uncertainties and inaccuracies. These factors include the following initial amplification cycles may not be exponential PCR amplification eventually plateaus after an uncertain number of cycles and low initial concentrations of target nucleic acid molecules may not amplify to detectable levels ... 10.1038 nmeth1007 869 Category Molecular biology Category Polymerase chain reaction Category Laboratory ..., each part will contain 0 or 1 molecules, or a negative or positive reaction, respectively.

For each molecule, the primer at the end to be joined is constructed such that it has a 5 overhang complementary to the end of the other molecule. Following annealing when replication occurs, the DNA is extended by a new sequence that is complementary to the molecule it is to be joined to.

  1. Ligase chain reaction

    The ligase chain reaction LCR is a method of DNA amplification . While the better known PCR carries out the amplification by polymerizing nucleotides, LCR instead amplifies the nucleic acid used as the probe. For each of the two DNA strands, two partial probes are ligated to form the actual one thus, LCR uses two enzymes a DNA polymerase and a DNA ligase . Each cycle results in a doubling of the target nucleic acid molecule. A key advantage of LCR is greater specificity as compared to PCR. ref Wiedmann M, Wilson WJ, Czajka J, Luo J, Barany F, Batt CA.
