How does NOMe-seq differ from standard accessibility assays?

NOMe-seq provides single-molecule footprinting of both nucleosomes and DNA methylation on the same fragment. This enables a much higher resolution of "poised" versus "active" states and clarifies the relationship between structure and silencing.

Can Creative Biolabs perform this analysis on FFPE samples?

Nucleosome positioning is sensitive to DNA fragmentation; however, we have developed optimized protocols specifically for high-quality FFPE samples. We recommend a pilot feasibility study to ensure your samples meet the required integrity thresholds.

Are sub-nucleosomal fragments analyzed as part of the service?

Yes. Fragments smaller than 147 bp often represent transcription factors or other DNA-binding proteins. Creative Biolabs includes sub-nucleosomal analysis to help you identify "licensed" regulatory sites that may be therapeutic targets.

Nucleosome Positioning (MNase-seq/NOMe-seq) Analysis Service

Creative Biolabs bridges the gap between complex chromatin biology and application by providing definitive maps of genomic "packaging." Our high-resolution platform identifies accessible regulatory elements versus those occluded by nucleosomes, a critical factor for drug discovery targeting chromatin remodelers. Utilizing single-molecule footprinting, we move beyond population-averaged data to resolve "all-or-nothing" regulatory states. This precision allows for the identification of rare, therapy-resistant subpopulations and novel distal enhancers, providing the high-fidelity structural data essential for validating epigenetic inhibitors and achieving breakthroughs.

Introduction to Nucleosome Positioning in Oncology

Nucleosome positioning is the primary determinant of genome accessibility, acting as the physical gatekeeper for all DNA-templated processes. Extensive research has established that nucleosome redistribution is not merely a consequence of cancer, but an early, widespread driver of the disease. In many adenocarcinomas, nucleosomes shift to positions favored by the underlying DNA sequence, thereby "licensing" oncogenic transcription factors to bind to previously occluded sites. By integrating MNase-seq with NOMe-seq, Creative Biolabs provides a hierarchical view of this process. This allows researchers to detect everything from individual histone footprints to the long-range coordination of chromatin fibers. Understanding these structural transitions is essential for unlocking the next generation of epigenetic therapies and identifying biomarkers that define the very earliest stages of oncogenesis.

Key Deliverables and Solutions

Creative Biolabs provides a comprehensive suite of analytical capabilities designed to deconstruct the architectural complexity of the cancer epigenome. Our specialized offerings include:

Integrated Multi-Modal NOMe-seq Mapping

We offer simultaneous assessment of nucleosome occupancy and endogenous DNA methylation on individual DNA strands. This dual-resolution approach allows researchers to distinguish between active, poised, and silenced chromatin states with single-molecule precision, revealing the epigenetic plasticity often hidden by bulk assays.

High-Depth mTSS-seq Targeted Enrichment

Our platform utilizes solution-based capture to enrich over 22,000 transcription start sites (TSSs). By focusing sequencing power on these critical regulatory hubs, we provide >100x coverage per nucleosome, ensuring statistically significant detection of subtle positioning shifts in early-stage tumors.

Sub-Nucleosomal Fragment & TF Footprinting

Beyond standard histone mapping, we analyze sub-nucleosomal DNA fragments to identify footprints of non-histone proteins. This service pinpoints exactly where transcription factors have been "licensed" to bind, offering an upstream view of the regulatory events driving oncogenic gene expression.

Advanced Bioinformatic Visualizations

We deliver more than raw data, providing publication-ready NOMePlot "lollipop" graphics and automated open chromatin identification. Our custom pipelines facilitate the discovery of bivalent promoters and distal enhancers, translating complex sequencing reads into clear, actionable biological insights for oncology.

Workflow

Our nucleosome positioning workflow is a streamlined, end-to-end pipeline designed to maximize data recovery from primary samples while minimizing experimental variability.

Publication

This review article provides a comprehensive perspective on nucleosome-omics, an emerging field that studies the epigenetic code and 3D genome landscape through the fundamental unit of chromatin, the nucleosome. It summarizes key technologies like MNase-seq and Micro-C, their development, applications, and corresponding bioinformatics tools. The article highlights how integrating nucleosome-level data offers fresh insights into genome regulation and spatial organization, concluding with future directions for this interdisciplinary research.

Why Choose Us?

Creative Biolabs stands at the forefront of epigenetic technology by integrating MNase-seq and NOMe-seq to achieve "fiber-level" resolution. Unlike standard assays that provide blurred cellular averages, our single-molecule approach reveals actual chromatin fiber configurations. These methodologies identify early-stage chromatin redistributions that precede DNA methylation changes in lung and colon cancers, providing a "predictive window" for oncogenic transformation. Our expertise in sub-nucleosomal fragment analysis identifies transcription factors "licensed" by nucleosome shifts. This upstream perspective enables developers to intervene before malignancy reaches advanced stages. We ensure optimized protocols maximize data yield from even the most limited research samples.
