Real Time RT-PCR

Real Time RT-PCR

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

Area of Science:

Molecular Biology
Biochemistry
Genetics

Background:

Quantitative reverse transcription-polymerase chain reaction (RT-PCR) is complex due to amplification variability and plateau phases.
Accurate RNA quantification is challenging, especially with limited sample amounts.
Existing methods like differential PCR offer improvements but may lack comprehensive internal controls.

Purpose of the Study:

To describe a robust method for quantitative mRNA characterization.
To address limitations in current quantitative RT-PCR assays.
To present a technique that provides internal controls for both sample comparison and amplification efficiency.

Main Methods:

Development and description of competitive and differential RT-PCR (CD-RT-PCR).
Coamplification of target genes with corresponding competitive templates.
Simultaneous amplification of two different genes within a single reaction vessel.

Main Results:

The described CD-RT-PCR technique allows for internally controlled quantitative gene expression analysis.
This method overcomes issues related to reaction variability and sample loading.
Provides a reliable approach for accurate mRNA quantification.

Conclusions:

CD-RT-PCR offers a superior method for quantitative mRNA analysis compared to standard RT-PCR.
The technique enhances accuracy by incorporating competitive and differential amplification strategies.
This approach is valuable for precise gene expression studies.
