Plasmid Verification Services

Confirm your plasmid constructs faster, more accurately and more affordably than ever before. Small and large constructs can now have the entire plasmid sequence done in a matter of days instead of weeks, without the hassle of having to design and synthesize primers. Eurofins uses a customized next-generation sequencing process to exceed the limitations, accuracy, and sensitivity of primer walking projects using Sanger sequencing techniques. Our quality-focused process uses unique molecular barcodes assigned to each sample to assure proper sample identification.  Our bio-informatics pipeline provides accurate data assembly compared to a reference sequence, variant calling, and allele frequencies.

  • Fast TAT compared to traditional primer walking techniques
  • Lower cost than traditional primer walking techniques
  • Verification of the entire vector sequence
  • Verify large plasmid constructs and large number of samples without impacting turnaround time.
  • No designing or purchasing of sequencing primers
  • Sequence assembly provided
  • Comprehensive report with variations from reference sequence and allele frequencies.

Service Details

  • DNA only. Please provide 200ng in 20ul.
  • Reference sequence for plasmid and construct required.
  • Minimum of 24 samples in 96-well format required in most cases, 8 if we are currently doing a run.
  • Sequencing for plasmids up to 50kb
  • Turnaround time depends on the size and number of samples.

Submission / Shipping Guidelines

  • Send samples in 96-well full skirted or semi-skirted PCR plates.
  • Ensure that your plate is tightly sealed to prevent sample cross-contamination. Avoidance of cross-contamination is essential.  NGS will identify sequences in very low quantities.  We recommend using heat seals or well-fitting strip caps.
  • Include a hard copy of the submission form with your samples.
  • Ship samples overnight. The address will be found in the submission form.
  • Send electronic copy of the submission form and reference sequence file to Also include a copy of the quote and payment information. Missing information may delay your project
  • Ship samples to:
