DNBSEQ-G50 NGS Sequencer detailed

Non-accumulative amplification errors
High precision base reading

By employing DNA Nanoballs (DNB) technology and its special linear amplification method, DNBSEQ-G50 effectively carries out high-rate amplification, while ensuring a reduced error rate.

Moreover, its nanochip spot design allows for signal enhancement while ensuring sequencing accuracy without signal interference. DNBSEQ-G50 uses improved combinatorial Probe-Anchor Synthesis (cPAS) technology to incorporate a fluorescent probe to a DNA anchor on the DNB. A high-resolution imaging system is then used to collect, read and identify optical signals.

This sequencing system not only avoids highly repetitive single-base reading errors caused by common physical signal errors, but it also produces high quality and high accuracy sample sequencing information.


No PCR amplification required. Our unique Rolling Circle Replication (RCR) technology employed in DNBSEQTM library construction eliminates errors associated with PCR. Only the original template DNA is used to generate copies and therefore amplification errors do not accumulate, resulting in greater accuracy for detection of significant mutations such as lndels and SNPs.

Optimized Patterned Array ensures that only one single DNB is attached at each spot, which results in greater saturation of DNB on the Flow Cell with unprecedented uniformity. This enables an industry-leading with reduced duplicate rate.

MGI platform’s unique library preparation method and RCR amplification results in much lower index hopping rates compared with other platf orms, at a rate of 0.0001%~0.0004%.
