Is PacBio expensive?
Briefly, PacBio sequencers produce low numbers of reads with high accuracy, while ONT sequencers produce higher numbers of reads with lower accuracy. Furthermore, PacBio Iso-Seq is commercially expensive, and ONT sequencing is more cost-effective.

How accurate is PacBio?
Capturing sequence data from native DNA or RNA molecules enables highly accurate long reads with >99.9% single-molecule accuracy.
How accurate is Illumina?
As shown below, a quality score of 20 represents an error rate of 1 in 100, with a corresponding call accuracy of 99%….SBS Technology Overview.
| Quality Score | Probability of Incorrect Base Call | Inferred Base Call Accuracy |
|---|---|---|
| 10 (Q10) | 1 in 10 | 90% |
| 20 (Q20) | 1 in 100 | 99% |
| 30 (Q30) | 1 in 1000 | 99.9% |
How accurate is Illumina sequencing?
Illumina sequencing Q scores are highly accurate. A whole-genome sequencing run (2 × 150 bp) of E. coli K12 MG1655 performed on the MiSeq system yielded 1.7 Gb of high-quality data. MiSeq data were trimmed to 2 × 100 bp to allow for a direct comparison with 2 × 100 bp reads from the HiSeq 2000 platform.
How much DNA is needed for PacBio?
Generally, DNA samples submitted to PacBio Service Providers for SMRTbell library prep and sequencing should have a minimum concentration of ~50 ng/μl (ideal range is ~150 – 200 ng/µl or higher; for 20 kb or larger libraries, the samples should have a concentration of ~ 200-300 ng/μl or higher).
What is a good Q30 score?
%Q30: The percentage of bases with a quality score of 30 or higher, respectively (see “Quality Scores Explained” below). Most Illumina runs will generate >70-80% Q30 data. This value is an average across the whole read length, and error rate increases towards the end of the reads.
What’s the difference between Illumina, Nanopore and PacBio?
This tweet apparently touched a nerve, starting a wide-ranging discussion about the merits of Nanopore versus Illumina versus PacBio and the utility (or not) of finished (or even decent quality) genomes. There were a few hundred tweets generated, by many of the experts in the field in additions to employees of at least one of the companies.
Which is better Oxford Nanopore or PacBio sequencing?
Although both PacBio and Oxford Nanopore generate longer reads compared to short read Illumina or Ion sequencing, the higher error rate of both the PacBio and Oxford Nanopore sequencers remain an issue needs addressing.
Which is more accurate Oxford Nanopore or Illumina?
Both companies are involved in genetic sequencing, with Illumina building bigger machines that are more accurate and Oxford Nanopore building smaller devices that are “less accurate” like the one seen below:
When did Illumina get their MinION sequencer from nanopore?
We were very excited to get our MinION sequencer from Nanopore 1.5 years ago… so many potential applications; sequencing in real time, use in the classroom, use in the field, not having to wait to get bacterial genomes, etc. But one thing lead to another and it languished in a drawer.
