What are replicates in PCR?

Technical replicates are repetitions of the same sample. They are amplifications that use the same PCR reagents and similar (but not identical) samples for the template reagents. Biological replicates take into account variation within a defined group.

What is real-time PCR?

Real-time PCR, also called quantitative real-time PCR, is a technique used to amplify and simultaneously quantify a targeted DNA molecule. It enables both detection and quantification.

What are real-time PCR applications?

Real-time PCR/qPCR assays have become the tool of choice for the rapid and sensitive determination and quantitation of nucleic acid in various biological samples, with diverse applications such as gene expression analysis, the detection of genetically modified organisms in food, and cancer phenotyping.

What is the difference between real-time PCR and PCR?

What is PCR and how is it different from real time RT–PCR? RT–PCR is a variation of PCR, or polymerase chain reaction. The two techniques use the same process except that RT–PCR has an added step of reverse transcription of RNA to DNA, or RT, to allow for amplification.

How many replicates are needed for qPCR?

According to your model, you will need at least 3 biological replicates. No statistics can be done on less than 3 samples in any case.

What is real-time PCR Why is it called so?

In order to robustly detect and quantify gene expression from small amounts of RNA, amplification of the gene transcript is necessary. This measurement is made after each amplification cycle, and this is the reason why this method is called real time PCR (that is, immediate or simultaneous PCR).

What is the difference between RT-PCR and RT Qpcr?

QPCR and RT-PCR are both terms used in biotechnology and utilized for the production of multiple copies of DNA. RT-PCR is used to amplify the reversed transcription of the DNA code; QPCR measures the amplification. 3. RT-PCR is for amplification, while qPCR is for quantification.

What are types of real-time PCR?

Two types of chemistry are available for the real-time quantitative PCR:

• DNA binding dye (Intercalating dye-based method)
• Sequence-specific probe (Hydrolysis Probe-based detection method)

Why it is called real-time PCR?

How is real-time PCR also known as quantitative PCR or qPCR different than traditional PCR?

QPCR is quantitative in nature, while RT-PCR is not. RT-PCR can be used without qPCR, for example to enable molecular cloning, sequencing or simple detection of RNA. Conversely, qPCR can be used without RT-PCR, for example to quantify the copy number of a specific piece of DNA.
