What Is The Difference Between RT-PCR And real-time PCR?


The real-time PCR and a reverse transcription-polymerase chain reaction are the most common methods use in molecular biology. Both ways generate multiple copies of DNA sequences, but PCR is faster. The main difference between these two procedures is that qPCR measures the amplification as it occurs, while PCR starts the amplification process. Hence, real-time PCR is faster than RT-PCR, which begins the amplification process and completes it in one step.

The PCR method is more efficient when it comes to amplification. The amplification of the template nucleic acid is done using an enzyme called reverse transcriptase. However, qPCR is also more quantitative, so it is more widespread. Besides amplification, both methods also have other advantages. PCR can . use for high-throughput screening, whereas qPCR requires a combination of amplification methods.

RT-PCR is a susceptible mRNA detection method. The PCR machine evaluate the resulting mRNA samples for low copy number (dsDNA). The qPCR results are use in a variety of clinical diagnostic tests. PCR is also known as real-time RT-PCR and can measure the relative amounts of mRNA in a sample.



RT-PCR relies on reverse transcription as its starting template. The mRNA is convert to cDNA by the enzyme known as reverse transcriptase. The cDNA is then use as the template for the qPCR reaction. RT-qPCR is a more accurate way to detect the mRNA transcripts. Both methods are a good choice for qualitative and quantitative analyses.

The real-time PCR is different from qPCR. PCR uses the dsDNA as its template. It also has a unique format. PCR is often use to detect the amount of RNA in a sample. Its application is in gene expression analysis. So, qPCR is the best choice when you want to see the amount of viral DNA in a piece.

PCR is an RNA-base amplification technique. A dye is use to determine the DNA concentration in a sample. The resulting signal depends on the amount of DNA in the selection. Unlike qPCR, which uses a single primer for each target, PCR detects more DNA than a single gene. Ultimately, this method is faster and more effective.

Primary Purpose

RT-PCR can . more effective for detecting viral RNA in samples than real-time qPCR, which uses a different primer. The latter is the more accurate method. Both RT-PCR and qPCR are often perform simultaneously. In a qPCR, the quantitative amplification is follow by the quantitative analysis. If the reaction has amplification, the byproduct will be proportional to the quantity of the template nucleic acid in the sample.

PCR is a quantitative method that allows for the analysis of RNA samples in the same sample. Unlike qPCR, PCR has a higher sensitivity and accuracy. Its primary purpose is to detect RNA in biological samples. The latter is use in molecular diagnostics. For example, a qPCR can detect HIV, a viral infection, or environmental contamination.


Real-Time PCR

RT-PCR is an improve version of real-time PCR, which uses a template of RNA instead of DNA. The real-time PCR method is quantitative and is suitable for monitoring and assessing gene expression. Its advantages over qPCR are its speed and precision. There are some disadvantages of PCR, though.

PCR is a faster version of conventional PCR, which requires more time. It can detect RNA in low-abundance species. In contrast, traditional blotting methods require a large amount of RNA, while PCR can handle a low amount of RNA. Both ways have their advantages. The real-time PCR is quicker, but it requires a more extend period than its predecessor.
