Sizing and quality assessment

We quantify and determine the integrity of your RNA or DNA prior to downstream applications such as library preparation. We also provide accurate quantification and sizing of NGS library.

Depending on the size of your fragments, and the type of sequencing you will do, we choose between three instruments:

  • Fragment Analyzer (AATI, Agilent) - We use this instrument for most of our sizing and quality assessment services.
  • FEMTO Pulse System (Agilent) - We use this instrument for high molecular weight (up to 200 kb fragments), very low concentration DNA sizing, or very low concentration RNA quality assessment.
  • 4200 TapeStation System (Agilent) - We use this instrument as an alternative to the Fragment Analyzer as part of some of our library preparation workflows.
