Quantitative real time polymerase chain reaction rt qpcr

Monitoring how many copies of DNA are produced by PCR If you go to the finish line of a race after the race is over, there is some information you can learn, but some you cannot. You can tell who ran the race, but not who won; the winners and losers will all be there standing around together.

Scanning just above the sample plate, the optics shuttle individually illuminates and detects fluorescence from each well with high sensitivity and no cross talk.

The optical system automatically collects data from all wells during data acquisition, so you can enter or edit well information on your own schedule. The optical filter sets are designed to maximize fluorescence detection for specific dyes in specific channels. At every position and with every scan, the optics shuttle is reproducibly centered above each well, so the light path is always fixed and optimal, and there is no need to sacrifice data collection in one of the channels to normalize to a passive reference.

Many factors contribute to the overall time it takes to get PCR results: Bio-Rad engineers have developed a complete thermal cycling system that will speed every step of the PCR process to give you what's really important — a shorter time from setup to results.

Protocol autowriter — generates an optimal protocol based on your polymerase, primers, and product length. Thermal gradient feature — identifies optimal annealing temperature in a single run.

Reduced-mass sample block — fast ramping and settling produce the shortest time to target temperature available in a thermal cycler. Superior Uniformity Precision of the temperature steps is critical for the rate and efficiency of PCR. To obtain reliable, consistent results, all sample wells must maintain proper temperature throughout each incubation step.

Key Features and Benefits

Rapid Arrival at Target Temperature A key component of overall protocol run time is the time required to reach target temperature, which is determined by the average ramp rate and the time needed for the sample block to reach thermal uniformity. Maximum ramp rate is less important because it can fluctuate significantly during the ramp.

The CFX96 Touch system produces high average ramp rates and tight uniformity during ramping to yield fast time to target temperature and faster protocol run times. Run times can be dramatically shortened — to less than 30 min — while still producing accurate quantitative results. Now you can tailor your runs around your schedule instead of tailoring your schedule around your runs.

Superior uniformity with rapid arrival at target temperature. This graph shows the temperature measured by probes in 15 wells across a sample block.

The traces are nearly indistinguishable due to the tight uniformity. Note the consistent high average ramp rate throughout heating and cooling. Thermal Gradient Efficient Optimization Determining the optimal temperature for primer annealing is crucial for efficient and specific amplification of product.

With the CFX96 Touch systems' thermal gradient feature, you can determine the optimal temperature for primer annealing in a single experiment, minimizing the use of precious samples and reagents and saving valuable research time. The thermal cycler provides exceptional temperature uniformity and reproducibility within each gradient zone, and the temperatures can easily be programmed and viewed on the touchscreen or onscreen in the software so you can quickly identify the optimal incubation temperature.

Thermal gradient experiment for optimizing annealing temperature. RFU, relative fluorescence units. O-ring hermetic seal extends the life of the heating and cooling elements.


Condensation from constant heating and cooling can degrade thermal electric modules TEscausing them to fail.

This substantially lengthens the life of TEs and guarantees outstanding thermal performance.Reverse transcription polymerase chain reaction (RT-PCR), a variant of polymerase chain reaction (PCR), is a technique commonly used in molecular biology to detect RNA transcript levels.

RT-PCR is often confused with real-time polymerase chain reaction (qPCR) by students and scientists alike, but they are separate and distinct techniques.

While RT-PCR is used to qualitatively detect gene. Introduction & Historical Timelines - PCR Technologies Guide. The Polymerase Chain Reaction (PCR) is used in all areas of biological science research, including the clinical, forensic and diagnostic fields and the widespread adoption of the PCR technique has re.

What Is Real-Time PCR? In conventional PCR, the amplified DNA product, or amplicon, is detected in an end-point analysis. In real-time PCR, the accumulation of amplification product is measured as the reaction progresses, in real time, with product quantification after each cycle.

The scientific, medical, and diagnostic communities have been presented the most powerful tool for quantitative nucleic acids analysis: real-time PCR [Bustin, S.A., Real-time polymerase chain reaction Quantitative polymerase chain reaction (Q-PCR) is a method by which the amount of the PCR product can be determined, in real-time, and is very useful for investigating gene expression.
