Source: Laboratories of Dr. Ian Pepper and Dr. Charles Gerba - The University of Arizona Demonstrating Author: Bradley Schmitz Reverse transcription-polymerase chain reaction (RT-PCR) involves the same process as conventional PCR — cycling temperature to amplify nucleic acids. However, while conventional PCR only amplifies deoxyribonucleic acids (DNA), RT-PCR enables the amplification of ribonucleic acids (RNA) through the formation of complementary DNA (cDNA). This enables RNA-based organisms...

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...

A One-Step RT-PCR assay for detection and genogroup identification of Norovirus isolates from children’s stools, that utilizes primers and TaqMan probes specific to the open reading frame 1 (ORF1)-ORF2 junction region, the most conserved region of the Norovirus genome is described. A non-commercial, cost-effective RNA extraction method is detailed.
FAQs
Analyzing cells individually exposes expression differences that disappear when many cells are combined. A bulk measurement can obscure the presence of distinct cellular patterns, whereas single-cell results can associate particular expression profiles with individual cells or cell groups. This resolution helps investigators relate molecular measurements to cellular identity and understand how diverse populations contribute to tissue function.
Reverse transcription converts messenger RNA from the captured cell into complementary DNA, creating a form that can be examined in the assay. PCR then amplifies selected targets so their expression can be measured from the limited material available in one cell. Together, these stages connect the cell’s messenger RNA content with analysis of specific genes.
A single-cell reaction begins with very little biological material, so contamination or handling-related variation can strongly affect the result. Careful handling and appropriate controls help distinguish expression that originated from the captured cell from signals introduced during processing. These safeguards are essential when comparing cells or identifying expression in rare populations.
The workflow proceeds from isolating or capturing one cell to lysing it, converting its messenger RNA into complementary DNA, and amplifying selected targets by PCR. Maintaining the connection between the captured cell and its reaction is central to interpretation. Controls and careful handling accompany this sequence so measured differences are less likely to reflect technical variation.
This approach is useful when researchers need to distinguish cell types, follow developmental changes, investigate disease-related expression, or examine rare cell populations. Its value is greatest when a combined sample would hide differences among cells. By linking selected gene-expression measurements to individual cells, it can clarify how heterogeneous tissues are organized and function.
Single-cell RT-PCR provides targeted gene-expression information from individual cells, while bulk samples can obscure cellular differences. It also complements broader sequencing approaches by offering a focused way to examine selected targets in specific cells. Used together, these approaches can connect overall molecular patterns with cellular heterogeneity, including variation that may be important in development or disease research.
