General Description
The Applied Biosystems 7900HT Fast Real-Time PCR System is the only real-time quantitative PCR system that combines 96- and 384-well plate compatibility and the TaqMan® Low Density Array with fully automated robotic loading-and now also offers optional Fast real-time PCR capability. The system is intended for laboratory analysis and is versatile and adaptable for many matrices.
Technical Description
High Throughput (HT) Real-time TaqMan® and other probe/dye polymerase chain reaction amplification of genes on a Peltier-based thermocycling apparatus.
Notes:
The model 7900 is popular when high throughput is a priority. When lower numbers of samples and lower cost is desired the model 7500 is often selected.
