Third-generation sequencing technology

Technology

In nanopore sequencing, DNA is passed through tiny pores embedded in a membrane. Each base is identified by how it alters the ionic current as it moves through the pore. Because this method can generate ultra-long reads, it’s particularly effective for sequencing large or complex regions—such as plasmids, large insertions, structural variations, and repeat-rich sequences.

Workflow

Experience a seamless workflow with Quintara: simply send us your DNA samples, and we'll prepare them into a sequencing library. The library is then sequenced on the Oxford Nanopore platform, generating long reads that are used to assemble your sequence of interest.

FAQ

How do I submit my samples for nanopore sequencing?

Once your order is successfully placed through the Quintara website, please print the order submission form, fold it so that the barcode is visible, and place it in a small bag with your samples. Then, deposit the bag into your nearest Quintara drop box, and our team will take care of the rest.

•  For labeling your PCR tubes, please clearly mark the first tube of the strip with your initials followed by the last two digits of your Order ID. For example, if your initials are YZ and the Order ID ends in 42, label the first tube as YZ42. The second tube should be labeled as 2, the eighth tube as 8, and so on. Please refer to the image below for the correct labeling format. Do not write the actual sample names on the tubes.

•  When submitting samples using 96-well plates, please ensure that there are no empty wells between samples, whether you are submitting by row or column. If using column numbering, label the first column (A01 as sample #1, H01 as sample #8). If using row numbering, label the first row (A01 as sample #1, A12 as sample #12).

What is the typical turnaround time for your Nanopore Sequencing service?

Our Nanopore sequencing service offers next-morning data delivery, with results typically available by 9am the following day. If you have not received your data by this time, please contact us promptly by emailing [email protected]. This will allow us to provide an update and resolve any potential issues, ensuring no further delays in receiving your sequencing results. We operate 7 days a week to support your needs.

How do I get in touch with support if I have questions about my order or need help with my data?

If you have any questions about your order or need assistance with your data, the best way to reach us is by emailing [email protected]. Our support team is ready to assist you with any inquiries or issues you may have.

What steps should I take if I need to cancel or modify my order after it has been placed?

If you need to cancel or modify your order after it has been placed, please contact us as soon as possible via email at [email protected]. We understand that circumstances may change and will do our best to accommodate your request. If the order is still in the early stages of processing, we may be able to make adjustments. However, once sequencing has begun, changes may not be possible. Please include your numeric order ID in the email for quicker assistance.

How can I request additional services after verifying the sequencing results, such as sample returns or DNA preparation from positive clones?

To request additional services, such as sample returns or DNA preparation from positive clones, please contact us via email at [email protected]. Provide your order details and specify the services you require, and we will assist you with the next steps.

How do I know if my sequencing results are ready for download, and how will I be notified?

You will receive an automatic email with a download link as soon as your sequencing data is uploaded to our website portal. You can either download the data directly from the link in the email or log into your Quintara account and access the data from the portal.
