Bio-Rad QX ONE Integrated Droplet Digital PCR System for Absolute Nucleic Acid Quantification

The Bio-Rad QX ONE Droplet Digital PCR System is an advanced integrated platform that combines droplet generation, thermal cycling, and droplet reading into a single instrument. Designed for molecular diagnostics, biotechnology research, and clinical laboratories, this system enables absolute quantification of DNA and RNA targets without the need for standard curves, making it essential for molecular cloning workflows and gene editing validation.

Key technical features include:

• Capacity: Processes up to 5 plates simultaneously with 96 samples per plate.
• Droplet Partitioning: Approximately 20,000 droplets generated per sample for precise molecular analysis.
• Detection Channels: Four fluorescence detection channels (FAM, HEX, Cy5, Cy5.5) plus an additional scatter channel enable multiplex assays.
• Thermal Gradient Capability: Supports thermal gradient cycling facilitating optimization of PCR conditions.
• Time to Results: Around 6.5 hours for the first plate and approximately 4 hours for each subsequent plate using a standard 2-step ddPCR cycling protocol.
• Dimensions and Weight: Measures 122 x 66 x 38 cm (76 cm including monitor), weighing 100 kg (220 lbs).

This benchtop digital PCR instrument offers high reproducibility, sensitivity for low-copy variant detection, and copy number variation analysis, making it widely adopted in synthetic biology research and biomanufacturing quality control. The streamlined hardware design reduces hands-on workflow steps, enhancing laboratory efficiency in bioprocessing and molecular quantification applications.

The system’s calibration status is recent (July 2023), and it has been validated for proper hardware and software functionality. For optimal operation, consumables such as droplet generation oil, reader oil, cartridges, and seals are required. The QX ONE platform supports absolute quantification critical in molecular diagnostics and biomedical engineering fields, ensuring robust and reproducible results in nucleic acid detection workflows.
