Both qualitative and quantitative polymerase chain reaction (PCR) testing for CMV are available as well, allowing physicians to monitor the viral load of people infected with CMV. The CMV pp65 antigenemia test is an immunofluorescence-based assay which utilizes an indirect immunofluorescence technique for identifying the pp65 protein of ...
SYBR Green fluorescence chart produced in real-time PCR Melting curve produced at the end of real-time PCR. A real-time polymerase chain reaction (real-time PCR, or qPCR when used quantitatively) is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR).
Cytomegalovirus (CMV) (from cyto-'cell' via Greek κύτος kútos - 'container' + μέγας mégas 'big, megalo-' + -virus via Latin vīrus 'poison') is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, [3] in the subfamily Betaherpesvirinae. Humans and other primates serve as natural hosts.
PCR is used to quantify integrated DNA. Reverse transcription polymerase chain reaction (RT-PCR) is a variation of PCR that can be used to quantify viral RNA. RNA is used as the starting material for this method and converted to double-stranded DNA, using the enzyme reverse transcriptase (RT) for PCR.
CMV, a common virus, that can be asymptomatic can cause birth defects, deaths when babies are born with it. No vaccine yet. Awareness and prevention are best.
A strip of eight PCR tubes, each containing a 100 μL reaction mixture Placing a strip of eight PCR tubes into a thermal cycler. The polymerase chain reaction (PCR) is a method widely used to make millions to billions of copies of a specific DNA sample rapidly, allowing scientists to amplify a very small sample of DNA (or a part of it) sufficiently to enable detailed study.
Quantitative Real-Time PCR (QRT-PCR), sometimes simply called Real-Time PCR (RT-PCR), refers to a collection of methods that use fluorescent dyes, such as Sybr Green, or fluorophore-containing DNA probes, such as TaqMan, to measure the amount of amplified product in real time as the amplification progresses.
Virus quantification is counting or calculating the number of virus particles (virions) in a sample to determine the virus concentration. It is used in both research and development (R&D) in academic and commercial laboratories as well as in production situations where the quantity of virus at various steps is an important variable that must be monitored.
