Fragment Analysis


3730xl DNA Analyzer (ThermoFisher Scientific)

  • Semi-quantitative analysis of the number of repetitions of the GAA expansion of the FXN gene by PCR.
  • Amplification range of 100-500 bp.
  • Includes TP-PCR systems to detect described expansions leading to amplicon sizes >500 bp.
  • It complies with the quality requirements specified by ISO 9001 and ISO 14001 in relation to the materials used in its manufacturing process.
  • For research use.

Imegen-Friedreich allows analysis of GAA triplet expansions in the FXN gene associated with Friedreich’s ataxia by conventional PCR and capillary electrophoresis. In addition, the kit offers a TP-PCR (triple repeat primed PCR) system to detect expansions not detectable with conventional PCR.
