Sample Prep Services

Do you like to use paramagnetic beads for DNA size selection?

We sure do!

Omega Bio-Tek has recently released a new formulation of their Mag-Bind® Beads called TotalPure NGS, which can be used to purify both DNA and RNA.  UO researchers can purchase aliquots of these beads from the GC3F for $7 per mL.

We have run a full series of tests to characterize their DNA size selection properties.

The GC3F offers full-service sample preps for many popular sequencing library types, including stranded mRNA-Seq, whole genome shotgun, 16S amplicon, 10X whole genome linked reads, single cell mRNA-Seq, PacBio, and many others -- including custom projects by request! Please contact us to inquire.

All library prep services include numerous quality control (QC) steps, including but not limited to:

  • Initial quantifcation and fragment analysis of your input samples
  • Barcoding of multiple libraries using uniquely dual indexed adapters
  • Size selection/dilution/concentration
  • qPCR quantification and fragment analysis of each barcoded sub-library
  • Final multiplexing based on qPCR results
