Frequently Asked Questions

How do I receive and open my sequence text and electropherogram files by E-Mail?

The zipped sequence files can be received using Eudora
or other E-Mail software. If you cannot receive zipped files, we can send the data via e-mail in either Bin Hex or MIME formats.Simple text files can be opened using Microsoft Word. Electropherogram files can be opened using Edit View (for Macs) or Chromas (for PCs) sequence analysis software.

All three of these applications can be downloaded for free from our links page or by clicking on the links highlighted above.

What results should I expect to get back?

Sequencing results; On average, we obtain read-lengths of 700 bp or more of sequence data with 99% accuracy. Our read lengths frequently go well over this, but read length is dependent upon several factors. Important factors in automated sequencing include such things as primer design, template DNA purity, template DNA concentration, and the GC content of the DNA template. Manual editing is the responsibility of the customer, but Eric, Carrie and Jaime are available for advice and tips. All customers will be provided with the simple text and electropherogram sequence files for their sequences. For customers receiving their results via E-Mail, the compressed files will be sent as zip attachments. ABI sequence analysis software is available for free. See our links page for downloads.
