Asymmetric PCR is a variation of PCR used to preferentially amplify one strand of the original DNA more than the other. The technique has applications in some types of sequencing and hybridization probing where having only one of the two complementary strands is required.
The touchdown polymerase chain reaction or touchdown style polymerase chain reaction is a method of polymerase chain reaction by which primers avoid amplifying nonspecific sequences. [1] The annealing temperature during a polymerase chain reaction determines the specificity of primer annealing. The melting point of the primer sets the upper ...
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 ...
PCR inhibitors are any factor which prevent the amplification of nucleic acids through the polymerase chain reaction (PCR). [1] PCR inhibition is the most common cause of amplification failure when sufficient copies of DNA are present. [2] PCR inhibitors usually affect PCR through interaction with DNA or interference with the DNA polymerase.
Christian Heinrich Maria Drosten ( German: [ˈkʁɪs.ti̯an ˈdʁɔs.tn̩] ⓘ, born 1972) is a German virologist whose research focus is on novel viruses ( emergent viruses). During the COVID-19 pandemic, Drosten came to national prominence as an expert on the implications and actions required to combat the illness in Germany.
DNA replication. DNA Polymerase I (PDB) Molecular mechanism of PCR. A strip of eight PCR tubes. The history of the polymerase chain reaction (PCR) has variously been described as a classic "Eureka!" moment, [1] or as an example of cooperative teamwork between disparate researchers. [2] Following is a list of events before, during, and after its ...
Master mix (PCR) A master mix is a mixture containing precursors and enzymes used as an ingredient in polymerase chain reaction techniques in molecular biology. Such mixtures contain a mixture dNTPs (required as a substrate for the building of new DNA strands), MgCl 2, Taq polymerase (an enzyme required to building new DNA strands), a pH buffer ...
Hot start PCR is a modified form of conventional polymerase chain reaction (PCR) that reduces the presence of undesired products and primer dimers due to non-specific DNA amplification at room (or colder) temperatures. [1] [2] Many variations and modifications of the PCR procedure have been developed in order to achieve higher yields; hot start ...
