The 7900HT Fast Real-Time PCR System is a 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 optional, integrated Automation Accessory provides maximum throughput. Up to eighty-four 384-well plates can be loaded at a single time for unattended operation; a bar code reader allows you to insert or substitute plates into the sample queue at any time.

• Fast PCR option reduces run time to about 35 minutes in a standard 96-well format, or about 55 minutes in a 384-well plate
• Continuous wavelength detection from 500-660 nm allows the use of multiple fluorophores in a single reaction
• Measure gene expression levels, detect and quantitate pathogens, perform allelic discrimination (SNP genotyping) assays as well as score the presence of gene sequences
• 96- or 384-well plate compatibility (including the TaqMan™ Low Density Array)
• Optional Enterprise edition software provides data analysis tools that support 21 CFR Part 11 guidelines providing data integrity and security
• Hands-free plate-loading and unloading provides true walkaway automation allowing you to increase your lab's productivity
• Proven assay development guidelines save time and money

High Throughput
The 7900HT System is a high-throughput real-time PCR system that detects and quantitates nucleic acid sequences. An optional Automation Accessory combined with 384-well plate capability make the 7900HT system ideally suited to meet the high-throughput requirements of today's drug discovery process. Key applications include gene expression quantitation and the detection of single nucleotide polymorphisms (SNPs) using the fluorogenic 5' nuclease assay.

Flexibility
The 7900HT system is a versatile research tool that can accommodate any real-time PCR need. User-interchangeable thermal cycling block formats let you select the format that’s right for your project, using industry-standard 96- and 384-well formats, as well as a novel 384-well TaqMan™ Low Density Array and a new Fast 96-well block that reduces run times from 2 hours to about 30 minutes. An easy automation upgrade path lets you add features to meet throughput demands. A Fast PCR option reduces run times from 2 hours to about 30 minutes.

Powerful Software
Using two automation software tools, Plate Utility and Automation Controller, most of the gene expression and SNP genotyping workflow is fully automated for high-throughput applications and requires minimal user intervention. You can now process 5,000 x 384 well plates (384 markers), which equates to 1.92 million genotypes. Using Relative Quantification (RQ) Manager, you can also process 200 x 384-well plates (96 detectors with quadruplicate data points⁄multiplexed endogenous control), which equates to 153,600 data points. Fully integrated into one complete Enterprise system, SNP Manager and RQ Manager eliminate data analysis bottlenecks in high-throughput SNP and gene expression research by allowing significantly more plates to be analyzed simultaneously. This reduces hands-on analysis time and simplifies the data analysis workflow.

Frequently asked questions (FAQs)

What is the threshold on the Applied Biosystems real-time PCR instruments and how do I set it?

The threshold is the numerical value assigned for each run that reflects the average dRn (change in fluorescence) during the initial cycles of PCR (baseline). The threshold is set by determining a statistically significant point (or value) above the baseline. You can manually adjust the threshold should you desire, to the place in the geometric phase where your replicates are tightest. For more information on how to manually set a threshold, please refer to the tutorial entitled Data Analysis on the ABI PRISM 7700: Setting Baselines and Thresholds (P/N 4370923). While this tutorial is based on the ABI PRISM 7700 system, the concepts are still valid for the Applied Biosystems real-time PCR instruments. You can search the document on our website by using the part number above as the keyword.

If you choose not to manually adjust the baselines and thresholds, the SDS software on the Applied Biosystems real-time PCR instruments has an Auto Ct algorithm that can be used to automatically generate baseline and threshold values for individual detectors. The algorithm calculates baseline and threshold parameters for a detector based on the assumption that the data exhibits the "typical" amplification curve. Experimental error (i.e. contamination, pipetting inaccuracies) can produce amplification curves that deviate significantly from a typical amplification curve. The data from these irregularities can affect the Auto Ct algorithm by causing it to generate incorrect baseline and threshold parameters for the associated detector. Therefore, Applied Biosystems recommends that after analysis of experimental data, you review all baseline and threshold parameters determined by the Auto Ct algorithm.

Can I import a standard curve for my real-time PCR data into the Design & Analysis Software (v2.x)?

It is possible to import a standard curve into the Design & Analysis Software (v2.x) if you are analyzing results from one of the following Applied Biosystems real-time PCR instruments:

What is the difference between a Fast 96-well and standard 96-well block?

There are two main differences between a Fast 96-well and standard 96-well block for the Applied Biosystems real-time PCR systems:
• Reaction well volume: The Fast 96-well blocks have 0.1 mL reaction wells and are compatible with 0.1 mL plates and tubes. The standard 96-well blocks have 0.2 mL reaction wells and are compatible with 0.2 mL plates and tubes.
• Ramp rate: The fast 96-well blocks have a higher maximum ramp rate than standard blocks for the same real-time PCR system. However, both the fast 96-well and standard 96-well blocks are capable of running standard and fast chemistry.

Note: For newer instruments (QuantStudio 3 and 5 Real-Time PCR Systems and later) "0.1 mL" and "0.2 mL" are being used in place of "fast" and "standard" as designations for the two 96-well block formats.

What qPCR instruments are compatible with Thermo Fisher Cloud?

All our real-time PCR instruments are compatible with Thermo Fisher Cloud Apps except the 7500 Fast instrument where the eds files alone are compatible with Thermo Fisher Cloud Apps.
