Q＆A
Everything you want to know about our platform.
Instrument Performance and Technical Principles
The DQ24 employs the globally innovative VibroJect vibration injection technology. A precision injection pump ensures the reaction mixture flows uniformly from the tip while the tip vibrates, generating uniform droplets via shear force. The droplet volume is programmable, ensuring reliable test results.
- Stable droplet volume enables absolute quantification without interference from external factors (e.g., reagents, consumable batches, temperature, air pressure).
- Fully automated operation with minimal sample dead volume.
- Integrated design eliminates the need for an external computer.
- 3–6 color fluorescence channels, compatible with a wide range of fluorescent dyes.
It detects low-abundance target nucleic acids with high sensitivity. The optical design eliminates signal crosstalk, ensuring monodisperse droplets and ultra-low dead volume. The sealed reaction prevents cross-contamination, while professional algorithms and a QC module guarantee precision.
The unique optical design avoids signal crosstalk, enabling precise identification of different fluorescence signals for accurate multiplex detection. Professional data processing algorithms further enhance detection accuracy.
Instrument Operation and Use
Operation is similar to ordinary qPCR: load samples directly into 8-tube strips, complete instrument setup in 1 minute, and run after configuring sample information, detection channels, and temperature programs. Beginners can master the process quickly with professional training.
It supports various sample resources, including throat swabs, sputum, bronchoalveolar lavage fluid, and blood. Two consumable specifications (1–16/24) are available, with a maximum throughput of 96 samples in 8 hours to meet different testing needs.
It operates efficiently, delivering complete results within 2 hours from sample loading—significantly faster than many comparable products—to provide rapid data output.
Basic molecular biology laboratory skills are sufficient. The simple workflow, combined with our professional training, allows operators to quickly conduct experiments.
Experimental Results and Data Processing
Multiple factors work together: optical design, droplet generation, sealed reactions, professional algorithms, and QC modules eliminate interference, prevent contamination, and enforce strict quality control.
Data is automatically stored in the built-in computer. The user-friendly software generates visual charts (e.g., scatter plots, histograms) for data analysis and supports export in PNG, PDF, and CSV formats.
Exported data uses universal formats, ensuring good compatibility with common tools like Excel and GraphPad Prism for further processing.
Instrument Maintenance and After-Sales Service
- Store in a clean environment with temperatures 15–40°C and humidity ≤85%.
- Regularly use the built-in FFU (fan filter unit) and UV disinfection.
- Consumables are cost-effective, and overall maintenance costs are low, supported by a detailed manual and after-sales guidance.
We provide 72-hour preliminary solutions via multiple channels (phone, remote assistance, on-site service). Spare machines are available locally for urgent needs.
- Free repair or replacement of parts for quality issues during the warranty period, covering both hardware and software.
- Post-warranty technical support is available at reasonable costs.
Application Scenarios and Fields
It is used for gene expression analysis, copy number variation (CNV) and single-nucleotide polymorphism (SNP) studies, cancer biomarker detection, and absolute quantification of NGS libraries.
- Food safety: Detecting pathogenic microorganisms and genetically modified components.
- Environmental monitoring: Analyzing environmental microbial nucleic acids.
- Agriculture: Crop gene detection and pest/disease monitoring.
Consumable Use
Key consumables include droplet generation oil, injection needles, amplification reaction plates, and plate seals—all specifically designed for DQ24 to ensure smooth experiments.
Consumables are sold in consumable kits, with each kit containing all necessary consumables for 96 tests.
Store in a dry, cool, and clean environment. For long-term storage, clean and place in a dedicated case at 15–25°C and 40%–60% humidity to prevent sealant aging or damage.
Reagent Kit Compatibility
As an open-platform system, DQ24 is compatible with digital PCR kits from major manufacturers. Both research-focused gene detection kits and clinical pathogen detection kits can be used, provided they meet the instrument’s technical parameters.
Note: Some kits may pose a potential risk of droplet fusion due to compositional differences; preliminary experiments are recommended to verify compatibility.
No. The instrument’s advanced technology ensures precise droplet generation, amplification, and detection analysis with compatible kits, maintaining accuracy, sensitivity, and reproducibility.
Choose based on your experimental goals:
- Research: Opt for reputable kits specialized in gene expression analysis or genetic research.
- Clinical diagnosis: Select clinically validated kits compliant with relevant standards.
Refer to kit specifications (e.g., sample types, detection ranges) and DQ24’s features to ensure compatibility.
Due to differences between digital PCR and qPCR principles, optimize the reaction system when using qPCR kits. Adjust primer/probe concentrations as needed to fit DQ24’s droplet generation and detection processes. Follow kit and instrument instructions strictly to avoid operational errors, and check buffer compatibility with consumables to prevent chemical reactions that may affect results.
