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]
Once a one-step RT-PCR kit with a mix of reverse transcriptase, Taq DNA polymerase, and a proofreading polymerase is selected and all necessary materials and equipment are obtained a reaction mix is to be prepared. The reaction mix includes dNTPs, primers, template RNA, necessary enzymes, and a buffer solution.
This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
A Riboprobe, abbreviation of RNA probe, is a segment of labelled RNA that can be used to detect a target mRNA or DNA during in situ hybridization. [1] RNA probes can be produced by in vitro transcription of cloned DNA inserted in a suitable plasmid downstream of a viral promoter.
Nucleic acid amplification is a technique used to produce several copies of a specific segment of RNA/DNA. [3] Amplified RNA and DNA can be used for a variety of applications, such as genotyping, sequencing, and detection of bacteria or viruses. [4] There are two different types of amplification, non-isothermal and isothermal. [5]
CryoEM of nucleic acid has been done on ribosomes, [7] viral RNA, [8] and single-stranded RNA structures within viruses. [ 9 ] [ 10 ] These studies have resolved structural features at different resolutions from the nucleobase level (2-3 angstroms) up to tertiary structure motifs (greater than a nanometer).
An RNA ladder is often run alongside the samples on an electrophoresis gel to observe the size of fragments obtained but in total RNA samples the ribosomal subunits can act as size markers. [11] Since the large ribosomal subunit is 28S (approximately 5kb) and the small ribosomal subunit is 18S (approximately 2kb) two prominent bands appear on ...
This protein resides in the protein complex nsp10-nsp14 that enhances replication fidelity by proofreading RNA synthesis, an activity critical for the virus life cycle. [10] Furthermore, the coronavirus proofreading exoribonuclease nsp14-ExoN is required for maintaining genetic recombination generated during infection.
