DNA Sample Submission Guidelines

DNA Sequencing:

To create an account on our iLabs site, download these instructions. Contact Mark Farrell​ with any questions or concerns when creating a new account.

  • ​​Standard Reaction/Data Collection: samples should be submitted in the following form:
    1. For plasmid DNA <12kb - provide 20 µL of DNA at a concentration of 40 ng/µL in water.  For PCR products 300-600bp - provide 20 µL of DNA at a concentration of 10 ng/µL in water.
    2. For a custom primer, please provide 10 µL at a 10 µM concentration and include the Tm of the primer.
    3. For template/primer mix please provide a 20ul volume of template at 40ng/ul and primer at 1uM final concentration.
    4. When submitting the same sample to be sequenced with multiple primers, please submit 20 µL volume of template for the first template-primer combination and 5 µL volume of template for each template-primer combination after that.
    5. For PCR fragment DNA- amplicons must be purified/treated prior to DNA sequencing. Please inquire for details and/or protocols. If you would like to submit PCR reaction, we can treat/prepare your sample for sequencing by purification or ExoSap treatment. Please inquire about cost and sample submission.
    6. The following standard primers are provided: M13F(-20), M13R,T7, T7 Term, SP6, T3, CMV-F, PGEX-F, PGEX-R, BGH-R, Lucif Ctrm Rev, GFP-R, pNTR1A-F, pNTR1A-R, PQE30-F, PQE-Tri-F, PQE-Tri-R, E-GFP-R, and V5 Ctrm Rev.
  • DNA samples that are submitted for standard ‘reaction/data collection’ service must be accurately quantified and prepared. Samples submitted with inaccurate concentrations and/or with contaminants present will result in poor sequence results or a failed reaction, which will still be billed to the user.
  • After processing the results will be available to you from the iLabs site. Please login and click on “View My Requests” tab. Click on the triangle corresponding to your order to expand it out. Your results will be attached to your order in the form of a .zip file.
  • The sequence will be repeated at no extra cost if there is an operator error or machine malfunction. Please provide accurately quantified, high quality DNA for successful results.
  • Automated sequencing is very sensitive to template and primer preparation.
  • It is essential that the templates be free from ethanol, salts and other contaminants, as these greatly affect the quality of the sequencing results.


Here are a couple programs available to view chromatogram files (.ab1):

Chromas Lite – from Technelysium

Finch TV – free download from Geospiza

Chromatogram Explorer – from DNAbaser

Human Identity Testing, Cell Line Authentication, and Mycoplasma Testing:

  • Please provide isolated/purified genomic DNA in a minimum volume of 15ul and a minimum concentration of 30ng/ul.
  • For ID and CLA testing only- a cell pellet can be submitted and we can perform the isolation for you. Standard DNA isolation rates apply.
