ABI PRISM® 7000 Sequence Detection System is a complete, real-time PCR system that detects and quantitates nucleic acid sequences. The ABI PRISM 7000 in real-time PCR also a cycle-by-cycle detection of the accumulated PCR product made possible by combining thermal cycling. In addition, fluorescence detection, and application-specific software in a single instrument.  Quantitative results are available immediately after PCR without additional purification or analysis.
