GaP uses Applied Biosystems Big Dye chemistry to prepare samples for the ABI 3730 DNA Analyzer (equipped with a 48-capillary array) and ABI 3130 Analyzer (equipped with a 4-capillary array). The quality of DNA sequence is directly related to template quality. With a good template, you can get up to 1200 bases of sequences from a single primer. As an educational facility, we will work with users to ensure that they have the correct amount of clean template and primers according to the following table.

*Please note:

  • For Sequencing Drop-Off Service samples and primers must be combined in a 7uL volume containing 3.2 pmol of primer and template at the appropriate concentration (listed in the table above). Templates must be in H2O (not TE).
  • Users must ensure that plasmids cleaned with mini- or midi-prep kits do not contain any ethanol (hinders the sequencing reaction) and have incubated long enough in water to allow for the homogeneous solution of DNA.




  • Training, consumables and reagents provided.
  • Template and primer(s) supplied separately by you.
  • Call to schedule a training session.

If your project does not lend itself to one of the above services please contact us at the GaP lab to discuss your individual needs.

Failed Sequences
We run positive controls with every sequencing and fragment analysis run. If we are unable to obtain quality sequence from our control, as well as from your samples, there will be no charge for that run. The GaP offers assistance in troubleshooting sample preparation.

Fragment Analysis Services

Please contact us to discuss your fragment analysis project.

Turn-around time is approximately 48 hours when working in 96-well plate format. Sample in individual tubes will be run when we can accommodate them on the instrument or on the following Friday, whichever comes first.
