What is Four-color multiplex reverse transcription polymerase chain reaction—Overcoming its limitations about?

Quantitative reverse transcription polymerase chain reaction (qRT-PCR) conducted in real time is a powerful tool for measuring messenger RNA (mRNA) levels in biological samples. Multiplex PCR is defined as the simultaneous amplification of two or more DNA (cDNA) targets in a single reaction vessel and may be carried out only using uniquely labeled probes for each target. Up to four genes can be detected in a multiplex 5' nuclease assay when using the appropriate instrument and the right combination of fluorophores. One of the more important advantages of multiplexing is a reduced sample requirement, which is especially important when sample material is scarce. Additional benefits are saving time on reaction setup and lower cost compared to singleplex reactions. Although multiplexing has several advantages over singleplex qRT-PCR, limited work has been done to show its feasibility. Few publications on four-color multiplex qRT-PCR have been reported, and to our knowledge no work has been done to explore the assay's limitations. In this paper, we report the first in-depth analysis of a four-gene multiplex qRT-PCR. To achieve a better understanding of the potential limitations of the q
