Service Overview
Eton uses Oxford Nanopore Technology (ONT) MinION devices, flow cells, and library preparation kits to perform whole-plasmid sequencing. Data is assembled on the EPI2ME platform using the wf-clone validation and wf-amplicon workflows.

Use Cases
- What technology should I use for my sequencing project?
- Use Nanopore for:
- Sequencing whole plasmids to validate important backbone sequences, especially for large scale plasmid preps.
- Sequencing large inserts without having to “primer walk”.
- Sequencing ITRs and other complex features.
- Use Sanger for:
- Sequencing or screening large number of clones, plasmids, or PCR fragments using one or two primers to cover a small region of interest and identify “hits”.
- Sequencing directly from colonies on agar (or glycerol stocks), especially where the validated clone is planned for scale-up by Eton’s DNA plasmid prep service
- Sequencing templates containing poly-A or other homopolymeric regions.
- Use Nanopore for:
Sequencing Service Types
- Purified Plasmid DNA.
- Purified PCR fragments from 500 bp to 5 kb.
Sample Prep Guidelines
For plasmids 25 kb and less:
- Required submission format: PCR strip tubes.
- Required concentration: 40 ng/u.
- Required minimum volume: 6 uL.
- Purified sample with no primers or dye added.
- For combined Sanger + Nanopore orders, please refer to Submission Guidelines here: https://www.etonbio.com/sequencing/faq_seq.php
For PCR amplicons between 500 bp and 5 kb:
- Required submission format: PCR strip tubes.
- Required concentration: 40 ng/u.
- Required minimum volume: 6 uL.
- Purified sample with no primers or dye added.
- At this time, we cannot accept mixtures or pools of PCR amplicons of varying sequences.
- For combined Sanger + Nanopore orders, please refer to Submission Guidelines here: https://www.etonbio.com/sequencing/faq_seq.php
