Illumina 5-base solution

One assay.
Dual insights.

Detect five DNA bases in a single assay while delivering concurrent genetic and epigenetic insights

The new standard in methylation sequencing

The Illumina 5-base solution enables direct detection of five DNA bases—adenine (A), thymine (T), cytosine (C), guanine (G), and 5-methylcytosine (5mC) at cytosine-guanine dinucleotide (CpG) sites—in a single sequencing workflow. By preserving nucleotide diversity and maintaining library complexity, the Illumina 5-base solution supports high sequence alignment rates and information-rich data. The optimized workflow integrates one library prep, one sequencing run, and one analysis pipeline to deliver dual omic insights without added assay complexity.

Key features and benefits

High-accuracy dual detection​

High-confidence variant calling (99.5% F1 score) and 60% higher CpG coverage vs whole-genome bisulfite sequencing (WGBS) enabled by a proprietary enzyme that preserves sequence complexity paired with optimized algorithms for improved read mapping.​

Exceptionally simple and fast​

Optimized, efficient workflow from sample to insight, with easy library preparation completed in as little as 6 hours and integrated analysis in ~1 hour for a 30× genome.​

Study design flexibility​

Support for both whole-genome and targeted enrichment workflows within the same 5‑base chemistry enables genome‑wide discovery or focused interrogation without changing assay fundamentals.​

Broad sample compatibility​

Nondamaging enzymatic conversion preserves DNA integrity, enabling consistent performance across diverse and challenging sample types, including low-quality genomic DNA (gDNA), cell-free DNA (cfDNA), and formalin-fixed, paraffin-embedded (FFPE) samples.

DNA and methylation: Dual insights, single assay

Bekim Sadikovic, PhD, Chief Scientific Officer at EpiSign Inc and Helge Lubenow, PhD, Chief Executive Officer at Heidelburg Epignostix discuss how the Illumina 5-base solution reveals hidden mechanisms of disease in the genome and epigenome in a single, streamlined, multiomic assay.

Applications

The Illumina 5-base solution is well-suited for applications that benefit from concurrent methylation and genetic variant information, particularly where DNA quality, complexity, and interpretability matter. Applications include:

 

 

Preferential solution to traditional NGS* methylation assays

 

Whole-genome studies

 

Targeted enrichment studies

 

Liquid biopsy, including cfDNA or ctDNA* studies

 

Tumor profiling, including FFPE* samples

 

Analysis of cfDNA fragmentation patterns (fragmentomics)

 

Population studies, including EWAS*

 

Disease research, including cancer, neurodegenerative, and genetic studies

 

Biomarker discovery

 

Aging studies

* cfDNA, cell-free DNA; ctDNA, circulating tumor DNA; EWAS, epigenome-wide association studies; FFPE, formalin-fixed paraffin-embedded; NGS, next-generation sequencing.

Testimonial

I am excited about a method that overcomes the loss of data caused by classical approaches. The lllumina 5-base solution converts 5mC to T, rather than converting unmethylated C. This approach preserves sequence diversity, yields significantly more usable reads, and enhances the signal, improving our ability to perform DNA methylation analysis.
