xGen Stubby Adapter-UDI Primers for Element
Barcodes designed with edit distance in mind to minimize any sequence errors from PCR or sequencing that might impact demultiplexing.
Stubby adapter and unique dual-index primer pairs for TA-ligation library preparation workflows where indexing by PCR is preferred. Available as single-use plates containing either 16 or 96 primer pairs, and a separate tube of stubby adapters with a matching number of reactions. The resulting libraries are intended for sequencing on an Element Biosciences sequencer.
xGen Stubby Adapter for Element is loaded in a multi-use tube and the xGen UDI Primers for Element are loaded into a single-use, 96-well plate containing a pierceable seal. The unique dual index (UDI) has a barcode length of 9 nucleotides. Each well contains one specific index pair for indexing one sample.
Sample multiplexing:
- 4 plex = wells A1-D1
- 8 plex = any column except column 6
- 12 plex = any row
- 16 plex = columns 1 & 2
xGen Exome Hyb Panel v2
- Shown to have higher on-target rate than leading array based competitors since each probe is individually synthesized and then added to the panel
- Consistency across lots as each probe was synthesized on a large scale prior to panel creation
- High end-to-end coverage of the RefSeq genes even in areas of high GC content
Our xGen Exome Hyb Panel v2 consists of 5' biotin–modified oligonucleotide probes that are individually synthesized and analyzed by electrospray ionization-mass spectrometry (ESI-MS) and optical density (OD) measurement. The probes are normalized before pooling to ensure that each probe is represented in the panel at the correct concentration. Probes that fail quality control are resynthesized. This manufacturing process gives the xGen Exome Hyb Panel v2 a unique advantage over array-derived pools in which missing or truncated probes cannot be identified before sequencing. IDT proprietary synthesis methods enable challenging probes—such as those with high GC and AT content—to be appropriately represented in the panel. The individual probes are synthesized on a larger scale than is used for array manufacturing, allowing IDT to produce a single, large lot of material that is aliquoted over time, providing consistent content from one aliquot to the next.
The xGen Exome Hyb Panel v2 consists of 415,115 probes that spans a 34 Mb target region (19,435 genes) of the human genome and 39 Mb of probe space—the genomic regions covered by probes. Our probes are designed using a new “capture-aware” algorithm and assessed with proprietary off-target analysis. All probes in the panel are manufactured under ISO 9001 standards, and then, mass spectrometry and dual quantification measurements of each probe are performed before they are pooled into the xGen Exome Hyb Panel v2. These measures ensure the quality of the probe and its appropriate representation in the final panel.

Product data
No need to sacrifice performance for speed. The paired IDT chemistry and Element’s novel Trinity workflow has demonstrated exceptional specificity across samples that it is highly reproducible across runs.
Figure 2. (A) and (B) Consistent flanked on-target percentage across samples and runs. (C) and (D) Consistent percent selected bases across samples and runs.
Libraries were constructed from 100ng input of Coriell NA12878 genomic DNA (gDNA) using the xGen™ DNA EZ UNI Library Prep Kit per the manufacturer’s instructions. Samples were then hybridized using an xGen Exome v2 Hybridization Panel following the xGen Exome Sequencing Kit Trinity for Element AVITI System Protocol. Hybridized libraries were sequencing using a Trinity 2x150 Sequencing Kit on an Element Biosciences AVITI™ Sequencing System. Following sequencing, samples were downsampled to 40 million reads before analysis using Picard.
High on-target coverage and uniformity with low duplicate read and drop out rates demonstrates you can achieve high efficiency exome sequencing, in less time, with consistent results across experiments to extract maximum insights from your samples.
