What does RT-PCR test for?
Real time RT–PCR is a nuclear-derived method for detecting the presence of specific genetic material in any pathogen, including a virus.
What is the first step in RT-PCR?
cDNA synthesis
One-step RT-PCR combines first-strand cDNA synthesis (RT) and subsequent PCR in a single reaction tube. However, two-step RT-PCR entails two separate reactions, beginning with first-strand cDNA synthesis (RT), followed by amplification of a portion of the resulting cDNA by PCR in a separate tube.
What is Qiagen Q solution?
Q-Solution changes the melting behavior of nucleic acids and can be used for RT-PCR systems that do not work well under standard conditions. When using Q-Solution the first time with a particular primer–template system, always perform parallel reactions with and without Q-Solution.
What are the differences between one-step RT-PCR and two-step RT-PCR?
In the one-step method, the reverse transcriptase is included in the same tube as the PCR. Two-step RT-PCR is highly sensitive, potentially more efficient, and allows for stocking of the cDNA for future use. However, this method is more time consuming and can require more optimization.

What are the two steps of RT-PCR?
In two-step RT-PCR, the RNA is first transcribed into cDNA using oligo-dT primers, random oligos, or gene-specific primers. An aliquot of the RT reaction is subsequently added to the real-time PCR reaction in a second tube.
Why is one-step RT-PCR better than 2 step?
There are advantages and disadvantages to both systems. The advantages to one-step real-time RT-PCR is that it is quicker to set up, less expensive to use, and involves less handling of samples, thereby reducing pipetting errors, contamination, and other sources of error.
