Reverse transcription loop-mediated isothermal amplification (RT-LAMP) is a one step nucleic acid amplification method to multiply specific sequences of RNA. It is used to diagnose infectious disease caused by RNA viruses. [1] It combines LAMP [2] DNA-detection with reverse transcription, making cDNA from RNA before running the reaction. [3]
In contrast to similar techniques such as polymerase chain reaction and ligase chain reaction, this method involves RNA transcription (via RNA polymerase) and DNA synthesis (via reverse transcriptase) to produce an RNA amplicon (the source or product of amplification) from a target nucleic acid. This technique can be used to target both RNA and ...
Reverse transcription polymerase chain reaction (RT-PCR) is a laboratory technique combining reverse transcription of RNA into DNA (in this context called complementary DNA or cDNA) and amplification of specific DNA targets using polymerase chain reaction (PCR). [1] It is primarily used to measure the amount of a specific RNA.
Reverse transcriptase again synthesizes another DNA strand from the attached primer resulting in double stranded DNA. T7 RNA polymerase binds to the promoter region on the double strand. Since T7 RNA polymerase can only transcribe in the 3' to 5' direction [15] the sense DNA is transcribed and an anti-sense RNA is produced. This is repeated ...
[42] [43] [44] KOD polymerase and some modified thermostable DNA polymerases (iProof/Phusion, Pfu Ultra, Velocity or Z-Taq) are used as a PCR variant with shorter amplification cycles (fast PCR, high-speed PCR) due to their high synthesis rate. Processivity describes the average number of base pairs before a polymerase falls off the DNA template.
RNA polymerase (purple) unwinding the DNA double helix. It uses one strand (darker orange) as a template to create the single-stranded messenger RNA (green). In molecular biology , RNA polymerase (abbreviated RNAP or RNApol ), or more specifically DNA-directed/dependent RNA polymerase ( DdRP ), is an enzyme that catalyzes the chemical reactions ...
Digital polymerase chain reaction (digital PCR, DigitalPCR, dPCR, or dePCR) is a biotechnological refinement of conventional polymerase chain reaction methods that can be used to directly quantify and clonally amplify nucleic acids strands including DNA, cDNA, or RNA.
A DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex.
