qPCR Assay for Rapid Virus Detection and Quantification
                     qPCR Assay for Rapid Virus Detection and Quantification
As an expert in providing solutions to assist virology and microbiology research,  
Creative Diagnostics has introduced its new qPCR Assay to the research community  
for virus detection and quantification, drug/therapy response, gene expression  
analysis, relative/absolute quantification, mutation analysis, and genotyping.
The direct identification of viral genomes in clinical samples by molecular techniques  
is one of the most important discoveries of the 21st century. Nucleic acid  
amplification techniques such as PCR, nucleic acid sequence-based amplification  
(NASBA), and the Lawrence Livermore Microbial Detection Array (LLMDA) are  
undoubtedly the leading technologies for rapid detection and identification of most  
known human viruses. PCR is an extremely sensitive assay that can amplify a specific  
region of DNA sequence 106-fold in vitro.
As one of the most widely used methods, PCR can effectively detect viral RNA by  
converting the RNA to DNA and then performing a PCR analysis called reverse  
transcription PCR (RT-PCR). Real-time PCR (or quantitative PCR, qPCR) quantifies the  
nucleotides of the virus in real time during the reaction. Detection of influenza virus  
by qPCR is faster than endpoint assays and its sensitivity is comparable to or better  
than cell culture methods. A previous study of respiratory syncytial virus in nasal  
secretions from children showed that qPCR was the most sensitive assay compared  
to immunofluorescence and cell culture-based assays. There are two types of qPCR,  
one probe-based, called TaqMan PCR, and the other dye-conjugated, called SYBR  
Green.
qPCR is widely used in experimental studies and clinical diagnosis of HIV-1, dengue  
virus and influenza virus. For example, the reduction of viral nucleic acids in infected  
cells is an indicator of the antiviral effect of the test article. In addition, qPCR is a  
sensitive, precise technique with a wide dynamic range that generates quantitative  
data. This is a powerful attribute as it allows the quantification of infection,  
progression of infection and any tissue predisposition in infectious diseases.
Creative Diagnostics now offers qPCR services to assist researchers in a variety of  
areas including viral detection and quantification, drug/treatment response, gene  
expression analysis, relative/absolute quantification, mutation analysis, and  
genotyping. These new qPCR assays are based on the latest technology developed by  
Creative Diagnostics scientists with extensive expertise in infection and analysis, and  
are rigorously tested to ensure accuracy and reliability.
In addition, Creative Diagnostics’ team of experts can quantify a variety of viruses,  
including CMV, DENV, HIV, influenza, RSV, RRV, SFV, SINV, VACV, and ZIKV. These  
services are tailored to clients’ project and include standard sample preparation  
procedures, primer/probe design and validation using validated viral standards for
quantification, and a full professional report.
