Overview
Illumina Cell-Free DNA Prep with Enrichment is a highly sensitive library preparation solution to detect low-abundance mutations from cfDNA samples. The workflow includes unique molecular identifiers (UMIs) for error correction and reduction of false positives, enabling accurate and sensitive detection of low-frequency mutations. Our fastest, highest quality, and most robust sequencing by synthesis chemistry, XLEAP-SBS chemistry is now enabled on the NextSeq 2000 (P4 flow cell) and NovaSeq X Systems.
Illumina Cell-Free DNA Prep with Enrichment has enhanced product attributes that enable greater efficiency for the labs, such as extended shelf life to six months and advanced change notification.
Fast workflow
Illumina Cell-Free DNA Prep with Enrichment offers a fast workflow for preparing sequencing-ready libraries in ~8.5–9.5 hours, with only ~2.5-3 hours of hands-on time. Researchers can go from extracted cfDNA to sequencing in a single day. The recommended read length for sequencing on the NextSeq 550 System is 2 × 149 bp. For sequencing on the NextSeq 2000, NovaSeq 6000, and NovaSeq X Systems, the recommended read length is 2 × 151 bp.
High-performance library prep
Illumina Cell-Free DNA Prep with Enrichment detects low-frequency variants, including SNVs, CNVs, Indels as variants, and gene fusions. The kit identifies small variants with allele frequencies as low as 0.2% from only 20 ng cfDNA with ≥90% sensitivity.
Streamlined sample-to-insights workflow
This kit is part of an integrated workflow with option for no manual touchpoints from sequencer to insights that (1) starts with cfDNA, followed by (2) sequencing on Illumina mid- and high-throughput systems, (3) highly accurate variant calling using the DRAGEN for ILMN cfDNA Prep with Enrichment App, and (4) option for variant interpretation through automated draft research report generation using Illumina Connected Insights.
Flexible content options
For enhanced content portability, Illumina Cell-Free DNA Prep with Enrichment is compatible with user-supplied enrichment oligo nucleotides from Illumina or third-party vendors, including single-stranded DNA (ssDNA) from Integrated DNA Technologies (IDT) and double-stranded DNA (dsDNA) from Twist Bioscience. The kit accommodates 55–2000 Kb (ssDNA) and 70–2000 Kb (dsDNA) panel content, enabling flexible study design.
Illumina Custom Enrichment Panel v2 provides dynamic feedback to optimize target coverage, making it the recommended solution for creating panels specific to your content of interest. DesignStudio software is a free, user-friendly, web-based assay design tool for creating custom sequencing panels.
What panels do I need?
Illumina Custom Enrichment Panel v2 can be used as spike-in panels, using the DesignStudio Assay Design Tool or with the Illumina Concierge design team.
What accessories do I need?
Index plates listed above are required to conplete the workflow. There are specific SKUs for manual and automation workflow. Illumina Custom Enrichment Panel v2 is a 120 bp, double-stranded probe panel designed using DesignStudio and includes enrichment oligos for hybridization capture.
