For sequencing plasmids or purified PCR products, this service is the most economical choice.

You provide your template and primer mixed in the same tube according to our Sample Submission Guidelines.



By choosing our Pre-Defined Service, you submit your template and primer in separate tubes, and a Azenta scientist will mix them when your sample is received. An additional charge applies in most cases.

For sequencing plasmids or purified PCR products, submit your template and primer in separate tubes according to our Sample Submission Guidelines.

Note: An Azenta Universal Primer can be used in this service at no charge.



This is a full-service option for sequencing of purified plasmids and purified PCR product samples with unknown concentration. For purified plasmids column-based PCR purifications, an Azenta scientist will measure and adjust the concentration of your template to optimize the sequencing reaction.

Note that if you have enzymatically-purified PCR products, we recommend that you submit these samples under the Pre-Mixed or Pre-Defined service levels. An accurate OD cannot be obtained from an enzymatically-purified template.

Submit template and primer separately according to our Sample Submission Guidelines.

Note: An Azenta Universal Primer can be used in this service at no charge.


Difficult Template Sequencing

Revolutionize your sequencing experience with our Difficult Template sequencing service, specifically designed for challenging templates featuring GC-rich regions or intricate secondary structures like hairpins. With a success rate surpassing standard workflows by over double, researchers can now save at least a day in their process. Versatile and efficient, this protocol accommodates various DNA types without the need for additional templates, offering unparalleled convenience and reliability.
