xGen™ for DNBSEQ™

Trusted IDT xGen NGS chemistries for emerging sequencers

Whether your project requires a basic indexing solution, or a more sophisticated design for higher accuracy, we have the products and expertise to deliver the right solution for DNBSEQ platforms.

xGen NGS—made platform-agnostic

Ordering

IDT has several solutions available for customers sequencing on a DNBSEQ™ platform. Our products support both WGS and targeted (hybridization capture) sequencing workflows.

  • IDT is the leading provider for high-purity PCR-indexing solutions for NGS—now proudly offering adapters for sequencing on a DNBSEQ™ system!
  • Barcodes designed with edit distance in mind, to minimize any sequence errors from PCR or sequencing that might impact demultiplexing
  • IDT is the first to offer stocked Universal Blocking Oligos for the DNBSEQ™ system, designed specifically for the native adapters

* Can be used if the stubby adapter included in the library prep kit is swapped out for the xGen Stubby Adapter for DNBSEQ

Use the xGen™ Stub Adapter-UDI Primers DNBSEQ™ products to perform indexing PCR on NGS libraries that require TA-ligation (using the included stubby adapter) for DNBSEQ-compatible library construction workflows that support indexing by PCR. Note, when using an IDT Library Prep Kit, the xGen™ Stubby Adapter DNBSEQ™ should be used instead of the adapter supplied in the IDT Library Prep Kit. For other commercial library prep workflows, refer to your library prep kit protocol for further instructions prior to using these products.

xGen™ Stub Adapter-UDI Primers DNBSEQ™ are available in two reaction sizes (16 and two sets of 96). xGen™ Stubby Adapter DNBSEQ™ is loaded in a multi-use tube and the xGen™ UDI Primers DNBSEQ™ are loaded into single-use plates.

  • Single-use plates: The indexing primers are loaded into single-use 96-well plates containing a pierceable seal. The unique dual index (UDI) has a barcode length of 10 nucleotides. Each well contains one index pair for indexing one sample.
  • xGen™ Stub Adapter-UDI Primers DNBSEQ™, 16 rxn
  • xGen™ Stub Adapter-UDI Primers DNBSEQ™ P1, 96 rxn
  • xGen™ Stub Adapter-UDI Primers DNBSEQ™ P2, 96 rxn

Sample multiplexing:

  • For an 8-plex use any column
  • For an (8 + N)-plex use any column + any N random wells in other columns

xGen™ products for DNBSEQ™ offers several benefits:

  • IDT is the leading provider of NGS indexing products, so you can be confident in the quality of your xGen™ Stub Adapter-UDI Primers DNBSEQ™
  • IDT is first to offer a stocked universal blocking oligo designed specifically for DNBSEQ™ libraries
  • Prevent adapter cross-hybridization—Adapter sequences are ligated to all library fragments, both on-target and off-target before enrichment. These adapter sequences can hybridize with each other during enrichment, creating a "daisy-chain" effect; off-target fragments are captured alongside on-target fragments which can impact sequencing efficiency. The xGen™ Universal Blocking Oligos for DNBSEQ™ bind to the native DNBSEQ™ adapters and help prevent adapter cross-hybridization
  • Universal blocking oligos reduce workflow steps by not requiring barcode-specific strand blocking; removes workflow steps that help reduce error; require less materials to store
  • xGen™ Library Amplification Primer Mix for DNBSEQ™ receives functional testing that ensures high performance library amplification post-capture PCR

Methyl-seq library preparation workflow comparisons

The xGen Methyl-Seq DNA Library Prep Kit has a post-bisulfite library preparation workflow to maximize library complexity by converting bisulfite-induced single-stranded fragments directly into library molecules. Traditional methods construct libraries from dsDNA using methylated adapters followed by bisulfite conversion that leads to significant library loss due to bisulfite-induced DNA fragmentation. The random priming methods are also post-bisulfite but have reduced library complexity due to a lower efficiency biased workflow (see Table 2; Figure 3).
