The use of Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) techniques has seen a recent upsurge in popularity due to the ongoing COVID-19 pandemic. This has led to an increased demand for RT-PCR kits, assays and reagents, including Reverse Transcriptases. In this blog post, we will explore what RT-PCR is, what Reverse Transcriptases are, and how they are used in One-Step PCR.

RT-PCR is a molecular biology technique used to detect and amplify RNA sequences. This technique involves two stages: reverse transcription and PCR amplification. In the first stage, Reverse Transcriptases are used to convert RNA to complementary DNA (cDNA). Once the cDNA is obtained, it is used as a template for amplification in the second stage, PCR amplification.

Reverse Transcriptases (RTs) are enzymes that catalyze the formation of cDNA from RNA. They are essential in RT-PCR because the PCR amplification of RNA is difficult due to its instability and low abundance. RTs overcome these limitations by converting RNA to stable cDNA, which can be amplified with a higher sensitivity and specificity.

There are different types of Reverse Transcriptases, including M-MuLV, AMV and GoScript. M-MuLV (Moloney Murine Leukemia Virus) was the first RT enzyme discovered and is still widely used in RT-PCR experiments. AMV (Avian Myeloblastosis Virus) RT is another commonly used enzyme that is highly sensitive to low RNA levels. GoScript RT, on the other hand, is a newer RT enzyme that offers improved performance, sensitivity and accuracy.

One-Step PCR is a variation of RT-PCR that combines the two stages of reverse transcription and PCR amplification in a single-tube reaction. This technique is preferred when a high throughput, sensitive and accurate detection is required. One-Step PCR has become an essential tool in the diagnosis of viral infections, including COVID-19.

One of the challenges with One-Step PCR is the inhibition of the RT and PCR enzymes by inhibitory factors in the sample. This can lead to a false negative result or reduced sensitivity of the assay. As a result, RT-PCR kits, assays and reagents that have been optimized to overcome these challenges are necessary to ensure reliable and accurate results.

In conclusion, RT-PCR techniques have become an essential tool in molecular biology, especially in the diagnosis of viral infections. Reverse Transcriptases are critical components of RT-PCR, facilitating the conversion of RNA to cDNA, which can then be amplified by PCR. One-Step PCR is a variation of RT-PCR that combines the two stages (RT and PCR) in a single-tube reaction. The use of optimized RT-PCR kits, assays and reagents is necessary to ensure accurate and reliable results.
