Non-accumulative amplification errors
High precision base reading
By employing DNA Nanoballs {DNB) technology and its special linear amplification method, MGISEQ-200 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. MGISEQ-200 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.
Flexible selection of read lengths
Rapid sequencing
MGISEQ-200 has been specifically designed for its temperature regulation system and sequencing enzyme. It has been possible to increase the number of types of supported read lengths without affecting the size of the device.
In addition, in order to meet the requirements for flexibility of throughput and time in different application scenarios, MGISEQ-200 has undergone improvements in the time required to carry out sequencing in different rend length modes. For example, a PE100 run can be completed using the FCS 100M read flow cell in 28 hours, and the FCL-500M flow cell will be completed within 45 hours.
The full list of read lengths are SE50, SE100, PE100, and PE150.
| Flow cell | Read length | Data output | Q30% | TAT |
| FCS-100M | SE100 | 10G | >80% | ~10h |
| PE100 | 20G | >80% | ~28h | |
| PE150 | 30G | >75% | ~41h | |
| FCL-500M | SE50 | 25G | >80% | ~11h |
| SE100 | 50G | >80% | ~18h | |
| PE100 | 100G | >80% | ~45h | |
| PE150 | 150G | >75% | ~64h |
