TaqMan PCR以及ABI-7700的简单介绍
------------------------------------------------

ABI PRISM® 7700 Sequence Detection System

Integrates a PCR-based assay with laser scanning technology to excite fluorescent dyes present in the specially designed TaqMan® probes. It is a fully integrated system for real-time detection of PCR. The system includes a built-in thermal cycler, a laser to induce fluorescence, CCD (charge-coupled device) detector, real-time sequence detection software, and TaqMan® reagents for the fluorogenic 5' nuclease assay. The cycle-by-cycle detection of the increase in the amount of PCR product is quantified in real time as the special probes, "reporter dye", fluoresces when the "quencher" is removed from the fragment during the PCR extension cycle.



Application of the "TaqMan® Probe" to Gene expression problems

To induce fluorescence during PCR, laser light is distributed to the 96 sample wells via a multiplexed array of optical fibers. The resulting fluorescent emission returns via the fibers and is directed to a spectrograph with a charge-coupled device (CCD) camera.



Sophisticated precision optics provides highly reproducible and quantitative results
* Continuous wavelength detection from 500-660 nm allows the use of multiple fluorophores in a single reaction
* The ability to perform multiple target quantitation in a single tube results in reduced sample and reagent costs
* Multiple chemistries enable versatile assay development
* Proven assay development guidelines save time and money
* Multiple applications including real-time quantitation, SNP detection, and +/- assay with an internal positive control provide the ultimate flexibility for your research needs
