XCeloSeq® Targeted cfDNA Enrichment Kits
NGS Library Preparation kits for cancer detection from liquid biopsy.
The XCeloSeq Targeted cfDNA Enrichment Kits generate high quality sequencing libraries for cancer detection from liquid biopsy (cfDNA) samples or FFPE-preserved material.
ENHANCED ERROR CORRECTION
XCeloSeq-generated sequencing libraries contain unique molecular identifiers (UMI) and a unique protocol design, which combine for enhanced error suppression and sensitivity.
​
STREAMLINED AND FAST WITH HIGHEST SAMPLE RETENTION
XCeloSeq protocols have been designed to be completed within 1 day with the fewest bead purifications and shortest hands-on times.
​
ENHANCED LIBRARY COMPLEXITY
All XCeloSeq products use the ATOM-Seq® capture chemistry which is built to be uniquely suited for use with liquid biopsy and FFPE material, delivering unrivalled library complexity
Sensitivity:
Allele frequency: ≥0.1%
Input Amount*:
Recommended: 5-50ng
Minimum: 1ng
Protocol Time:
Total: 5h 40m
Hands-on: 1h 20m
The XCeloSeq Targeted cfDNA Workflow
Using the ATOM-Seq DNA capture method, Unique Molecular Identifiers (UMIs) and universal adapter sequences are incorporated directly into available 3' ends of every original sample molecule. Then, two rounds of target-specific PCR generate sequencing-ready libraries.
ATOM-Seq DNA Capture​
Hands-on Time: 10 minutes
Incubation Time: 1 hour and 45 minutes
Starting materials (cfDNA, FFPE DNA or high quality genomic DNA) are combined with the Adapter Template Oligo (ATO).
Incorporation of universal priming site and Unique Molecular Indicator directly onto original starting molecule.
Two rounds of Nested,
Target-Specific PCR
Hands-on Time: 1 hour and 10 minutes
Incubation Time: 2 hour and 35 minutes
Multiplexed target-specific primers are paired against a universal primer which binds the extension that was added by the ATO reaction. Together these amplify target mutation hotspots by PCR.
A second round of target-specific PCR using a nested primer maximises on-target rate of sequencing, and incorporates dual-index sample barcodes (i5 and i7).
Sequencing-ready library in 5 hours, 40 minutes.

XCeloSeq Indexing Kits (SEQ005)
Dual indexing primers to enable sample multiplexing. Each kit contains either eight i5 or eight i7 sample index primers.
Kits can be purchased separately to suit your multiplexing requirements.
These primers can be used as substitutes for the default pair of sample indexing primers included in any XCeloSeq Library preparation kit, including XCeloSeq Targeted cfDNA kits.
* Higher quantities within this range will improve maximum sensitivity, recommended maximum is 50 ng. The product supports capture with down to 1.0 ng of cfDNA, however this will lead to reduced sensitivity. Enzymatically fragmented FFPE is also supported as an alternative starting material.
