Minimizing Contamination While Maximizing Efficiency

The DNBelab-D4 is a portable, fully automated system that prepares libraries from DNA or RNA samples to DNA Nanoballs (DNBs) in approximately 2.5 to 3.5 hours. During the library preparation process, each droplet—including both the sample and waste—is encapsulated by sealing fluid within the sample preparation cartridge. This design isolates droplets from ambient air, preventing aerosol generation. Each reaction zone operates independently, eliminating aerosol contamination and sample cross-contamination. (Figure 1)

This enclosed system minimizes contamination and accelerates turnaround time, making it ideal for pathogen identification, metagenomics, targeted sequencing, whole genome sequencing, and converting third-party libraries for DNBSEQ compatibility.

Digital Microfluidics Technology

 The DNBelab-D4 uses advanced digital microfluidic technology, controlling microliter droplets via electrowetting to move, merge, mix, and dispense samples precisely on a single cartridge for efficient preparation.

Automatic Quantification

The sample preparation cartridge is divided into five zones: sample, reaction, reagent reservoir, quantification, and product.

The quantification zone enables automatic quantification, eliminating the need for manual steps.

Key Applications

Microbial Whole Genome Sequencing (WGS) 

 The DNBelab-D4 enables rapid and efficient sample preparation for microbial whole genome sequencing (WGS). In just 3 hours and 20 minutes, the D4 produced ample DNBs (≥10 ng/μL) ready for sequencing on the DNBSEQ-E25 and DNBSEQ-G99 sequencing platforms.

Both sequencers delivered high-quality data, with scaffold counts below 100 and over 99% coverage across all bacterial samples. These results showcase the DNBelab-D4’s capability to provide comprehensive and accurate microbial genome analysis in a streamlined workflow.

Shotgun Metagenomics (mNGS) 

The DNBelab-D4 system provides rapid and accurate sample preparation tailored for shotgun metagenomics. This study prepared a mixture of human and microbial community DNA on the DNBelab-D4 and sequenced on the DNBSEQ-G99 platform, producing DNBs in just 2 hours and 50 minutes. The results accurately identified pathogens consistent with those in the microbial community standard, maintaining correct relative abundance rankings across varying sample ratios.
