† Amplification must be done using a uracil-tolerant polymerase. IDT recommends the UG Amplification kit (catalog
# 20020007), available from Ultima Genomics
Whole genome sequencing (WGS) workflow
We offer xGen for Ultima solutions for both PCR-free and PCR-dependent WGS workflows, each with flexible options depending on the number of samples.
- xGen PCR-Free Adapters for Ultima Genomics
- For applications with adequate gDNA input to support a PCR-free workflow, or when indexing by ligation is preferred
- xGen Indexing Primers for Ultima Genomics
- For applications where indexing by PCR is preferred
- Requires uracil-tolerant PCR mix, found in the UG Amplification Kit available from Ultima Genomics (catalog # 20020007)
- xGen Stubby Adapter (catalog # 10005974 or 10005924, sold separately) may be required; refer to Table 1 and Figure 1 for details
All xGen sample indexing products for Ultima are loaded into single-use 96-well plates containing a pierceable seal. The sample barcode has a length of either 15 or 17 nucleotides—consult the index list and plate map for further details. Each well contains material for indexing one sample.
Sample multiplexing:
- For an 8-plex, use any column
Please contact us with any questions.

Target enrichment workflow
Confidently perform target enrichment via hybridization capture with the following xGen for Ultima HybCap products:
- xGen HybCap Adapters for Ultima Genomics
- Used for library construction prior to hybridization capture
- Requires conditioning with the Ultima Genomics UG Library Amplification Kit prior to sequencing*
- xGen HybCap Lib Amp Primers for Ultima Genomics
- Designed to increase yield for sequencing post-hybridization capture
- xGen Universal Blockers for Ultima Genomics
- Reduces non-specific adapter interaction during hybridization
* Different adapters are required for hybridization capture due to the modifications found on the native Ultima adapters. Due to this, after hybridization capture, conditioning of the final library using the UG Amplification Kit available from Ultima Genomics (catalog # 20020007) is required prior to sequencing on the Ultima platform.
All xGen sample indexing products for Ultima are loaded into single-use 96-well plates containing a pierceable seal. The sample barcode has a length of either 15 or 17 nucleotides—consult the index list and plate map for further details. Note that there is no difference in the index sequences between products used for WGS or target enrichment. Each well contains material for indexing one sample. The xGen Universal Blockers and HybCap Lib Amp Primers for Ultima are both delivered in multi-use tubes.

Frequently asked questions
What methods are recommended to quantify my libraries prepared using xGen™ PCR-Free Adapters for Ultima?
Libraries prepared using xGen PCR-Free Adapters for Ultima must be quantified prior to sequencing by qPCR using library quantification primers and standards available from Ultima (UG Library Quantification Kit, Ultima part number L09) and a 2X SYBR® qPCR master mix which must be purchased separately.
Quantification using fluorometric or electrophoretic methods are not suitable for quantifying libraries prepared using xGen PCR-Free Adapters for Ultima.
What plate sealing guidelines should I follow when fewer than 16 or 96 libraries are prepared?
You should use an adhesive plate seal over the punctured but unused wells to prevent future cross‑contamination. Do not heat‑seal the plate twice.
How will my xGen™ PCR-Free Adapters for Ultima or xGen™ HybCap Adapters for Ultima be delivered?
How will my xGen™ Indexing Primers for Ultima be delivered?
Can universal or standard blocking oligos be used with libraries made from the xGen™ Adapters and Indexing Primers for Ultima?
No. Only xGen™ Universal Blockers for Ultima should be used for hybridization capture of libraries prepared using the xGen™ Adapters and Indexing Primers for Ultima. Other xGen™ blocking oligos available from IDT are not compatible with Ultima libraries.
What buffer should I use to dilute the xGen™ Stubby Adapter, xGen™ PCR-Free Adapters for Ultima, and xGen™ HybCap Adapters for Ultima?
We recommend using a buffer made of 10 mM Tris, 0.1 mM EDTA, and 100 mM NaCl, pH 8.0 (such as the IDT NGS Adapter Buffer, Cat. No. 10006743) to dilute the xGen™ Stubby Adapter, xGen™ PCR-Free Adapters for Ultima, and xGen™ HybCap Adapters for Ultima.
Keeping the adapters duplexed requires a buffer with a high salt concentration.
What amount of xGen™ Adapters or Indexing Primers for Ultima should I use for library prep?
Which sequencing platform should be used for the xGen™ Adapters or Indexing Primers for Ultima?
Can adapter ligation be carried out in the provided 96-well plate of xGen™ PCR-Free Adapters for Ultima, or xGen™ HybCap Adapters for Ultima?
No, this is not recommended.
All our plate-based indexing products contain overage to allow for pipetting error, so we recommend pipetting directly out of the index plate and into a separate reaction plate, or tube.
What is the shelf life and recommended storage conditions for the xGen™ Adapters or Indexing Primers for Ultima?
Store all xGen™ Adapters or Indexing Primers for Ultima at –20°C. The date of manufacture is included on the product label and its corresponding Certificate of Analysis, which can be found by searching by batch/lot number on the product label. IDT recommends using the products within 1 year of the date of manufacture.
What is the shelf life and recommended storage conditions for the xGen™ Universal Blockers for Ultima?
