DNA Sequencing Core Facility

DNA Sequencing Core Facility

The DNA Sequencing Core Facility provides DNA sequencing services to investigators at CMMT and CFRI, as well as off site researchers. It is equipped with the ABI Prism 3130xl Genetic Analyzer, a 16-capillary fluorescence-based DNA analysis system.

In addition to DNA sequencing, the 3130xl system supports a variety of applications including comparative sequencing, DNA fragment analysis, and genotyping. Skilled staff members are ready to lend their expertise in sequencing PCR products, plasmids, and BACs with a turn-around time of 1 to 3 days.

Since 2002, the facility has run over 96,000 analyses of samples for over 165 research groups at the CMMT, CFRI, UBC, SFU, UVic, and numerous hospital, industry and government research groups.


Sequencing is performed on an ABI 3130xl 16-capillary automated genetic analyzer. Samples are typically run on a 50 cm capillary yielding 800 to 900 bp with results typically available in one to three business days. We offer both Full Service sequencing of your DNA templates, or a Ready-to-Run service if you prefer to do your own sequencing reactions.

We sequence single or double stranded DNA from plasmids, PCR products, BAC, PAC and cosmid templates as well as sequencing of bisulfite converted methylated DNA utilizing the ABI BigDye v3.1 Terminator chemistry. Alternate chemistries (ABI BigDye V1.1 and dRhodamines) are utilized as required for difficult to sequence templates.

Sequence data is provided electronically as analyzed ABI files (.ab1), though are available in other formats (see protocol notes).

As successful sequencing reactions are highly dependent on the quality and accurate quantitation of templates provided, please adhere to the following points for all samples submitted:

  • Purify templates using commercially available nucleic acid purification kits (see protocol notes for recommendations)

  • Samples must be normalized to the same concentration with the following minimum quantities and concentration ranges:

    Sample type Minimum quantity Concentration range
    Plasmid 300 ng 30 to 100 ng/ul
    BAC, PAC, or Cosmid 600 ng 100 to 1,000 ng/ul
    PCR Products   10 to 20 ng/ul
    100 bp 5 ng  
    500 bp 20 ng  
    1,000 bp 35 ng  
    2,000 bp 60 ng  

  • The actual concentration of each sample must be provided.
  • There is a $3/reaction surcharge if samples must be adjusted to normalize the concentrations to the same concentration within the required range.

  • Re-suspend template and primers in dH2O or 10mM Tris pH8.0 to 8.5, no TE.

  • Standard primers are provided (see primers). Alternatively, please provide non-standard primers at 3.2pmol/ul.

  • If submitting more that 7 samples with the same primer sets, please submit samples in 8-strip PCR tubes or 96-well plates.

  • Discounted pricing available if primers are pre-mixed and all samples are standardized to the same concentration, within the ranges specified above, and provided in a 96-well plate or 8-strip PCR tubes (see below).

A more economical DNA sequencing option is available for plasmids and PCR products. The Pre-Mixed Samples Service special pricing is available if the following sample submissions requirements are followed:

  • Primers must be pre-mixed with your plasmid or PCR product samples.

  • Samples must be submitted in 8-strip PCR tubes or 96-well plates.

  • Primer concentration, total sample volume, and sample concentration must meet the following specifications:

    Sample type DNA Length
    (including vector)
    DNA Amount
    Primer Amount
    Total Volume
    Plasmids <6kb 300 10 15
      6-10kb 400 10 15
      >10kb 500 10 15
    PCR Products <1000bp 10ng per 100bp 10 15
      1kb to 2kb 80ng to 120ng 10 15

Please provide the facility with your cycle sequenced and purified sequencing products (in 8-strip PCR tubes or 96-well plates if more than 6 samples). The facility will run your samples, confirm sequencing results, and provide results in ABI .ab1, or your preferred electronic format. See our protocol notes for details.
