Qpcr (real-time pcr) protocol explained
The LightCycler® 480 SYBR Green I Master is a PCR hot start reaction mix with only one part. For product detection and characterization, it includes FastStart Taq DNA Polymerase and DNA double-strand-specific SYBR Green I dye. Since the mix comes as a ready-to-use real master reagent, all that is needed for reaction setup is the addition of template DNA and primers. The mix is suitable for high-throughput applications in 96- or 384-well plates and can be used with various forms of DNA (e.g., genomic, cDNA).
The SYBR Green I Master for the LightCycler® 480 Instrument contains reagents, including SYBR Green I dye, for amplification and detection of DNA with the LightCycler® 480 Instrument. The kit is suitable for gene detection and quantification using hot start PCR assays.
SYBR Green I is a DNA dye that only works on double-stranded DNA. The SYBR Green I dye, which is included in the reaction mix, binds to the amplified PCR products during each step of DNA synthesis, allowing the amplicon to be identified by its fluorescence.

Quantitative PCR is a technique for determining the relative or absolute degree of gene expression. When the degree of fluorescence gives signal over the background and is in the linear portion of the amplified curve, all qPCR uses fluorescence to detect the threshold period (Ct) during PCR. The accurate quantification of qPCR is dependent on this Ct value.
Use plates that are compatible with the system you’re going to use. Using ABI’s Optical 96-Well Fast Thermal Cycling Plates with the ABI7500 Fast PCR system (Part No.: 4346906). With this panel, use ABI Optical Caps (Part No.: 4323032).
Your plate should resemble the one shown above. It should provide a standard curve for each gene being measured, as well as a water regulation (no cDNA) for each gene. Make sure you’re using the right qPCR optical plates and caps for the unit you’re using. A standard PCR plate will not suffice.
Quantitative PCR necessitates the use of a particular machine that can detect SYBR fluorescence when conducting PCR. (The ABI 7500 Fast Real-Time PCR system, for example, is used in the Young lab.)

The GoTaq® qPCR and RT-qPCR Systems are ready-to-use 2X master mixes containing BRYT Green® Dye, a fluorescent DNA binding dye with limited PCR inhibition that offers greater fluorescence enhancement and amplification efficiency than SYBR® Green I.
The GoTaq® Systems are compatible with most real-time PCR instruments that use normal or quick cycling because of their rapid hot-start activation and processive enzymes. GoScriptTM Reverse Transcriptase is included in the 1-Step and 2-Step RT-qPCR Systems to allow efficient synthesis of first-strand cDNA in preparation for PCR.
The GoTaq® qPCR Master Mix is a 2X master mix for real-time quantitative PCR that is ready to use. The GoTaq® qPCR Master Mix combines GoTaq® Hot Start Polymerase, optimized buffer, and BRYT Green® Dye to provide reliable real-time PCR with earlier quantification period values and broad-range detection. For quantitative, real-time PCR, these characteristics result in improved reliability, reproducibility, and sensitivity.
Single-copy identification using qPCR. From 10-fold serial dilutions (0.01ng to 100ng) of human genomic DNA, the GAPDH gene was amplified and identified. The normal curve for the different dilutions is shown in the inset (Slope=-3.2; R2=0.995). Absorbance spectroscopy was used to determine the yield and purity of the package.

A betacoronavirus called SARS-CoV-2 has been identified as the etiologic agent of the 2020 pandemic outbreak, according to phylogenetic analysis. A diagnostic test with high sensitivity and specificity is needed for public health interventions. The World Health Organization (WHO) finds RT-PCR to be the gold standard for diagnosis. A low-cost diagnostic test is needed to detect low viral loads and perform large-scale screening. We produced a low-cost test that can detect SARS-CoV-2 in this study. We successfully screened negative cases of SARS-CoV-2 using an auxiliary technique for molecular diagnosis based on the SYBR Green RT-PCR methodology. Our findings revealed a set of primers with high specificity and no homology with other Coronovideae family viruses or human respiratory tract pathogenic viruses, only complementarity for rhinoviruses/enteroviruses and Legionella spp. The PCR products had a high specificity due to the optimization of the annealing temperature and polymerization time. For negative SARS-CoV-2 screening, we established a more cost-effective and time-efficient system. Via guidelines for isolation techniques, this approach can be used on a wide scale to reduce panic and economic burden.
