Illumina Complete Long Read Technology
Introducing Illumina Complete Long Read sequencing technology
This novel technology will bring more light to even the darkest corners of the genome. Illumina Complete Long Reads help resolve the most challenging regions of the genome and makes long-read sequencing accessible and streamlined by enabling short and long reads from a single platform.
Illumina Complete Long Read technology powers a portfolio of novel, high-performance assays using standard next-generation sequencing (NGS) workflows and trusted Illumina sequencing by synthesis (SBS) chemistry.
Products:
- Illumina Complete Long Read Prep, Human: Our most accurate and most comprehensive human whole-genome assay. Enabled by leveraging the strengths of highly accurate short and long reads across the human genome.
- Illumina Complete Long Read Prep with Enrichment, Human: A flexible, cost-effective solution to enhance coverage of known challenging-to-map regions with targeted long reads where they provide the most value. Compatible with predesigned and custom panels enabled by Illumina DesignStudio software.
- Illumina Complete Long Read Prep with Enrichment and Human Comprehensive Panel: Predesigned, optimized panel to enhance coverage of challenging-to-map regions within protein-coding genes using Illumina Complete Long Read Prep with Enrichment.
Key features
Accessible and cost-effective
Both long and short reads from your existing Illumina sequencing system. Easily integrates into standard NGS workstreams without specialized equipment. Comprehensive, push-button cloud analysis available on BaseSpace Sequence Hub or Illumina Connected Analytics.
Robust and flexible
Low (50 ng) DNA input, tolerant to contaminants and freeze/thaw cycles. Generate contiguous long-read sequences with N50 of 5-7 kb with as low as 10 ng input DNA. Highly flexible long reads that can scale from small targeted panels up to long-read whole genomes.
Scalable and streamlined workflow
Simple, streamlined, and automation-friendly library prep without specialized equipment. Assay up to 3000 long-read whole genomes or tens of thousands of targeted long-read panels per year using NovaSeq X Series. Reduce batching requirements by assaying smaller sample numbers of targeted long reads using lower throughput consumables.
Highly accurate
Powered by proven Illumina SBS and DRAGEN analysis on BaseSpace Sequence Hub or Connected Analytics. Capable of F1 score (SNVs + indels) of 99.90% for human whole genomes as measured by PrecisionFDA Truth Challenge v21 and enabling phased sequencing of regions > 100 kb.
How Illumina Complete Long Read technology works
Tagmentation is used to fragment and normalize long fragment sizes. Long fragments are “land-marked” to capture single-molecule, long-read information and amplified. Land-marked fragments can be enriched or move directly to tagmentation to standard libraries for sequencing. Marked and unmarked data are combined to generate highly accurate complete long reads.

Clear haplotype assignment
Illumina Complete Long Reads can resolve highly polymorphic regions like the HLA-A gene. Uniform coverage in the HLA region enables accurate phasing of HLA alleles.
Detection of large deletions
A heterozygous 180 bp deletion in the SEMG1 gene is clearly detected by both Illumina Complete Long Reads and on-market long reads.
Resolution of STRC from its pseudogene
Both Illumina Complete Long Reads and on-market long reads clearly resolve the 23 kb STRC gene from its pseudogene, pSTRC.
Enhanced coverage in challenging regions of protein-coding genes
Low-coverage regions in the RHCE gene are resolved using Illumina Complete Long Read Prep with Enrichment and the Human Comprehensive Panel.
High-quality performance across a wide range of DNA inputs
Illumina Complete Long Read Prep, Human with 5 ng to 1200 ng input DNA (in triplicate) generates similar data quality for N50 and phase block N50. N50 is the sequence length of the shortest contig (or phase block) at 50% of the total assembly length.
Human phasing
Perform phased sequencing with Illumina Complete Long Reads to identify co-inherited alleles, haplotype information, and phase de novo mutations.
Compatible with trusted Illumina sequencing systems
Illumina Complete Long Read technology is compatible with the NovaSeq X Plus, NovaSeq X, and NovaSeq 6000 Sequencing Systems, giving you access to both long- and short-read data on the same instrument.
