Minor Variant Finder Software

The improved sensitivity achieved using the FREE Applied Biosystems Minor Variant Finder Software makes Sanger sequencing the ideal choice for oncologists and/or pathologists to call low frequency somatic variants (5% or below) where the number of relevant targets is often limited. The software requires no change to your current Sanger sequencing workflow.

Benefits include:

  • Call minor variants at a detection level as low as 5%
  • Sequence a moderate number of targets at a low cost
  • Confirm next generation sequencing findings in alignment view and Venn diagram
