Whole Plasmid Sequencing is offered through our parent company, Eurofins Genomics. All links below will redirect to www.eurofinsgenomics.com. You will need to create a new account with Eurofins Genomics to place orders. 

Fast, accurate, and affordable long-read sequencing

Confirm full plasmids faster, more accurately, and more affordably than ever before with Whole Plasmid Sequencing. NGS generation 3 technology has made it possible to quickly sequence whole plasmids in a fraction of the time and without the hassle of having to design and synthesize primers. The typical turnaround time for whole plasmid sequencing is 1 business day measured from when the samples are received. There is no minimum requirement for the number of samples.

How do I ship samples?

1. Dropbox – we have a nationwide network of dropboxes. If you want a box for your lab, let us know! Email GenomicsSupport@eurofins.com to request a box.

2. Free Digital Shipping Labels – digital shipping labels are provided free for a vast majority of sequencing orders. You can select the option for digital shipping label during checkout.

3. Ship the samples using your normal carrier – If using your own carrier, we highly recommend shipping overnight/next-day delivery to ensure the samples do not degrade in transit.

How do I get results?

Results are available to download from the order history page. You will be emailed when the results are ready as well. Currently, 95% of results are delivered within 1 business day from receiving the sample.


No Primers Needed

Unlike short-read sequencing, whole plasmid sequencing does not require any primers.

No library prep needed

Unlike conventional next generation sequencing methods, no library prep is required.

No Shipping Cost

You can use our existing network of dropboxes to submit samples or print a free digital shipping label at checkout. If you would like a dropbox for your lab, let us know! Email GenomicsSupport@eurofins.com to request a box.


Oxford Nanopore’s reports the raw read accuracy is 98.3% and the consensus accuracy for SNPs is 99.6% with 50X coverage.

FAQ / 

Currently >90% of results are delivered by 5pm ET the same day the samples are received.

Any number of samples is welcome. There are no minimums or limitations.

Dropboxes are available in many locations. Also, Eurofins is the only sequencing company that offers free digital shipping labels on >95% of orders. Take a look at our sample submission page for details.

The equipment vendor reports accuracy of 99.3%. The research community has reported accuracy between 93-98%.

There are pros and cons of every sequencing method. Sanger sequencing and Oxford Nanopore sequencing (ONT) are both methods for determining the sequence of nucleotides in a piece of DNA. Typically Sanger is consider the most accurate method for short-read sequencing and NGS is better for long-read sequencing.

Overall, the choice between Sanger sequencing and ONT will depend on the specific needs of the application. Both methods have their strengths and limitations, and the appropriate method will depend on factors such as the length and quality of the DNA sample, the desired level of accuracy, and the cost and availability of the necessary equipment.




Short read sequencing


  • Widely used and well-established method
  • High accuracy and precision
  • Can be automated for high-throughput sequencing
  • Chromatogram makes it easy to visually interpret results
  • Limited read length (typically up to 1000 base pairs)
  • Requires relatively large amounts of high-quality DNA
  • Requires reassembly for covering longer regions.
  • Difficult to sequence repetitive regions without gaps and resolve large variations.

Long read sequencing

(Whole Plasmid)

  • Long read lengths (up to several hundred thousand base pairs)
  • Can sequence a wide range of sample types, including low-quality and degraded DNA
  • No primer design required
  • All data from one sample


  • Lower accuracy compared to Sanger sequencing, particularly for shorter reads
  • More expensive per base pair compared to Sanger sequencing
  • ·Cannot resolve single bases.
Sample type Size Category Length Concentration Min volume Price per sample
Plasmid Regular 2.5 – 25 kb 30 ng/uL ≥10 uL $15
Large 25 – 125 kb 50 ng/uL ≥20 uL $30
XL 125 – 300 kb 50 ng/uL ≥40 uL $60

Absolutely. Using our free barcode labels is not required, but always an option.

You can send it and we can sequence it, but we cannot predict or promise the analysis outcome. The customer would take on the risk of these orders.

It is easy. Go to our online ordering page.

We will be rolling out the new order page across portal sites, marketplaces, and punchouts very soon. At the moment, please submit orders on the main www.eurofinsgenomics.com website.

It really depends on the sample quality. We cannot guarantee the level of coverage at this time. A good sample submitted properly will typically yields hundreds or even thousands of sequencing reads. Consensus coverage depends on how many reads are full-length plasmids and how many, if any, degraded.

  1. .fasta file (for consensus data): we will provide a clean, complete consensus sequence for each plasmid.
  2. .gbk GenBank file (for consensus data): a pLannotate map in the GenBank file format.
  3. (OPTIONAL) .fastq file – raw data on reads. Email support to request fastq files.
  4. Histogram file: the hisogram file provides a visual representation of the plasmid and raw read data for deeper insight into your samples (image).
  5. .html pLannotate map (for consensus data): a plasmid map for each sample.

The probability of failure is low when using WPS, although it can still happen. If you wish to resequence a failed sample, contact Genomics Support. Unfortunately, we must charge for failed samples since it requires more time and energy than a normal run on the machine. If the sample fails a second time, all data points to a problem with the sample and we cannot resequence. In that scenario, we advise the customer to either send a new sample or troubleshoot the sample from their end.

We will be adding this service soon but not yet.
