How much is a real time PCR machine?

A simple PCR machine like Bio-Rad T100 thermal cycler has a list price of 4912 USD (with a promotional price of 2595 USD in the US) as of Jan 30, 2019. The cost of rtPCR systems ranges anywhere from 15,000$ for some RotorGene models to over 90,000$ for QuantStudio 12k.

Is real time PCR quantitative?

Real-time PCR results can either be qualitative (the presence or absence of a sequence) or quantitative (copy number). Quantitative real-time PCR is thus also known as qPCR analysis. In contrast, PCR is at best semiquantitative.

Is qPCR more sensitive than PCR?

There was no statistically significant difference in the number of positive tests between the SYBR real-time PCR and assays targeting ompA or rpoB genes; however, qPCR assay was found significantly more sensitive in testing skin samples compared to conventional assays targeting ompB, gltA, or hrtA genes (p<0.01).

What exactly is PCR?

Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). It is routinely used in DNA cloning, medical diagnostics, and forensic analysis of DNA.

What is a standard in qPCR?

A standard curve is used to determine the efficiency, linear range, and reproducibility of a qPCR assay. These values are valid only for the concentration range of the serial dilutions used to generate the standard curve.

How do you analyze PCR?

PCR products are most commonly analyzed by agarose gel electrophoresis. The results can be visualized by ethidium bromide or non-toxic dyes such as SYBR® green. The intensity of the band can be used to estimate the amount of product of given molecular weight relative to a ladder.

How do you read real time PCR results?

Real time PCR results are visualized in an amplification plot. Fluorescence is represented on the Y axis, whereas the number of PCR cycles is plotted in the X axis.
