PCR Purification


Industry-leading, gold-standard Sanger sequencing is performed on our ABI 3730xl platforms designed for high throughput without sacrificing quality. The high optical sensitivity and uniformity across a 96-capillary array, with the use of advanced polymers for separation, ensure that you receive the best quality sequencing results to support your applications.

We are equipped and experienced in the many complexities of Sanger sequencing, whether you need a single tube or a stack of plates to be sequenced. We are excited to expand your research under RUO or CLIA/CAP-regulated workflows.

Types of Service

Plasmids or PCR products


Provide your template and primer pre-mixed in a single well/tube according to our sample submission guidelines.


Template and primer may be sent separately. View our sample submission guidelines and provide your own primers, or select one of our universal primers free of charge.

Difficult Templates

There are some templates where our proprietary sequencing reactions may be necessary to improve your sequencing results and avoid needing repeats. If your template is GC-rich, contains difficult repeats, hairpins and secondary structures or long homopolymers, then select our difficult template workflow (click here for more information).

PCR Purification

Retrogen utilizes an enzymatic PCR cleanup method to remove unincorporated primers and dNTPs to ensure good-quality templates are available for your sequencing reactions.


Clinical Sequencing

CLIA/CAP-regulated workflows are available, allowing you to expand your clinical workflow and report Sanger sequencing results.
