high-speed, high flexibility and ultra-high throughput,Turbocharge your sequencing


The DNBSEQ-T7 is the latest generation of world leading sequencing technology from MGI. With capacity of 6Tb in 24 hours the throughput is best in class. The T7 has changed the game for high throughput sequencing labs by offering sequential loading. You no longer need to compromise between throughput and turn around time. The T7 allows for sequencing loading of up to 4 flow cells at a time.

The MGISEQ-T7 brings production logic to the laboratory. The unit is capable of sequencing 6Tb in 24 hours and allows for continual loading of flow cells whilst the unit is sequencing. Each flow cell is run independently. The run times for a PE100 flow cell are 20 hours, and PE150 flow cell is 24 hours.


  • Utilises DNB Technology to minimise duplicates and remove barcode hopping.
  • Unrivalled throughput of 6Tb in 24 hours.
  • Sequential loading of up to 4 flow cells provides ideal turn around time with out compromising on throughput
  • PE150 and PE100 read lengths

Performance Parameters

No. of Flow Cell per run 4
No. of lanes/Flow Cell 1
Max. reads/Flow Cell* 5000M
Read lengths PE100 | PE150

* The maximum number of effective reads are based on the sequencing of an internal standard library. Actual output may vary depending on sample type and library preparation method.

Read Lengths Data Output Data Quality Q30* Run Time**
PE100 1~4T >85% ~20h
PE150 1.5~6T >80% ~24h

*The percentage of base above Q30 is the average of an internal standard library over the entire run. The actual performance is affected by factors such as sample type, library quality, and insert fragment length.

**Run time includes Flow Cell loading,sequencing, and base calling.

MGI DNBSEQ™ Technology Highlights


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


Optimized Patterned Array ensures that only a 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 detection capability and an average duplicate rate below 3%.


MGI platform’s unique library preparation and RCR amplifica­tion results much in lower index hopping rotes compared with other platforms, at a rate of just 0.0001%-0.0004%.
