DNA Fragment Analysis
Genetic marker analysis experiments rely on the detection of changes in the length of a specific DNA fragment to indicate the presence or absence of a genetic marker. Our DNA Sequencing team offers a fast and reliable automated DNA fragment analysis service where fluorescently labeled DNA fragments are electrophoretically separated using the ABI3730xl Genetic Analyzer.
For selected applications (Microsatellite and MLPA), we also offer the final data interpretation as an add-on service for samples labeled with 6-FAM. We perform quality DNA sizing, allele calling, and relative quantitation using the GeneMapper v6.0 analysis software package.
Accurate size calling, consistent band intensities, and low run-to-run migration
variations by electrophoresis on ABI 3730xl DNA Analyzer
Sizing to within 1 bp resolution for fragments in the approximate size range of 50 bp to
Supported dye labels: 6-FAM (blue), NED (yellow), PET (red), VIC (green)Please note: Data analysis can only be performed here at the Core when 6-FAM is selected. Analysis of any other dye label or multiplexing more than one dye is to be performed by the end user.
Multiplex option (up to 4 fluorescent dyes)
Sizing by comparison with GeneScan 500 LIZ Size Standard
On-site data interpretation (Microsatellite and MLPA applications only!) using
GeneMapper v6.0 analysis software (add-on service option)
Please note: Data interpretation of NED, PET, VIC, and multiplexed samples are the responsibility of the user. The core will analyze data when samples are labeled with 6-FAM only.

Supported DNA Fragment Analysis Applications:
- Microsatellite Analysis (short tandem repeats (STRs), variable nucleotide tandem repeats (VNTRs))
- MLPA Analysis (multiplex ligation-dependent probe amplification)
We are performing our standard fragment analysis services utilizing an ABI 3730xl protocol that has been specifically developed and optimized for Microsatellite and MLPA applications.
