Here are typical specifications for a Quantitative PCR Machine:
1. **Throughput:** The system's throughput can vary based on the number of samples that can be processed in a single run. This can range from a few samples to high-throughput systems capable of analyzing hundreds of samples simultaneously.
2. **Detection Method:** Most quantitative PCR systems use fluorescent dyes or probes to monitor the amplification of the target DNA during the PCR reaction. Common detection methods include SYBR Green dye or specific fluorescent probes like TaqMan probes, molecular beacons, or other hydrolysis probes.
3. **Detection Channels:** Systems can be designed to detect fluorescence in one, two, or more channels, allowing for multiplexing, which enables the simultaneous detection of multiple targets in a single reaction.
4. **Temperature Control:** Precise control over thermal cycling is critical. The system will typically provide accurate and stable temperature control for denaturation, annealing, and extension steps of the PCR process.
5. **Software and Data Analysis:** The system may include software for instrument control, data analysis, and result interpretation. This may involve the calculation of cycle threshold (Ct) values, quantification of targets, and the generation of standard curves.
6. **Compatibility:** It is important to consider the compatibility of the system with various consumables such as PCR plates, tubes, and different chemistries for PCR.
7. **Connectivity:** Some systems might offer connectivity options for easy data transfer, remote monitoring, and integration with laboratory information management systems (LIMS).
8. **Dynamic Range and Sensitivity:** The dynamic range and sensitivity of the PCR System are crucial in detecting and quantifying low-abundance targets and in accurately measuring high-abundance targets.
9. **Interchangeable Blocks:** Certain systems offer interchangeable blocks, allowing users to switch between different PCR formats, such as 96-well plates, 384-well plates, or tube strips.
10. **Multiplexing Capability:** Some systems are capable of multiplexing, enabling the detection of multiple targets in a single reaction. This can be valuable for high-throughput studies or when working with limited sample material.
