Diagenode Megaruptor®3 Automated DNA Shearing System

Overview

The Diagenode Megaruptor®3 is an automated, high-precision DNA shearing system engineered specifically for long-read sequencing applications. Unlike sonication- or enzymatic-based fragmentation methods, the Megaruptor®3 employs controlled microfluidic hydrodynamic shearing—generating reproducible, size-selected double-stranded DNA fragments without thermal denaturation, sequence bias, or enzymatic artifacts. This principle ensures preservation of native DNA integrity and methylation patterns, making it ideal for third-generation sequencing platforms including PacBio SMRT, Oxford Nanopore Technologies (ONT), and Helicos systems. The instrument delivers fragments ranging from 2 kb to 75 kb, enabling optimal library preparation for de novo assembly, structural variant detection, haplotype phasing, and epigenomic profiling. Its closed-tube, non-contact architecture eliminates carryover risk and supports unattended operation across multiple sequential runs.

Key Features

• Fully automated, walk-away operation with pre-programmed and customizable shearing protocols
• Integrated 7-inch high-resolution capacitive touchscreen interface with intuitive icon-driven navigation
• Non-contact microfluidic shearing technology—no probes, no consumable wear parts, no tube clogging
• Consistent fragment size distribution across diverse sample types: genomic DNA from blood, tissue, FFPE, microbial cultures, and environmental isolates
• Robust performance independent of DNA concentration (0–150 ng/µL), salt content, buffer composition, or ambient temperature fluctuations
• Real-time LED status indicators (multi-color) provide visual feedback on cycle phase, error conditions, and completion
• Validated compatibility with downstream magnetic bead-based purification kits (e.g., AMPure XP, SPRIselect)

Sample Compatibility & Compliance

The Megaruptor®3 accepts standard 1.5 mL low-bind tubes and accommodates input volumes between 20 µL and 200 µL. It maintains consistent performance across variable DNA sources—including high-molecular-weight (HMW) DNA extracted via phenol-chloroform, column-based kits, or automated extraction platforms. No calibration or routine maintenance is required beyond standard lab cleaning protocols. The system is designed to support Good Laboratory Practice (GLP) and quality-controlled NGS workflows. While not a regulated medical device, its architecture aligns with principles referenced in ISO/IEC 17025 for testing and calibration laboratories, and its audit-ready operation log meets internal traceability requirements for research integrity. All firmware updates are version-controlled and documented per Diagenode’s quality management system.

Software & Data Management

The embedded control software provides protocol storage, parameter logging, and timestamped run records—including fragment size target, total processing time, and user ID. Exportable CSV logs support integration into LIMS environments. No external PC is required for operation; however, optional Diagenode Cloud Connect enables remote monitoring and firmware update notifications via secure HTTPS. Audit trails include operator login, parameter modification history, and error event timestamps—supporting compliance with institutional data governance policies. Software does not implement FDA 21 CFR Part 11 electronic signature functionality but retains full raw operational metadata for retrospective analysis.

Applications

• Preparation of HMW DNA libraries for PacBio HiFi and Revio systems
• Nanopore sequencing library construction for ultra-long-read (ULR) and adaptive sampling workflows
• Chromatin conformation capture (Hi-C, Micro-C) requiring intact megabase-scale chromatin domains
• Metagenomic assembly from complex environmental or host-associated microbiomes
• Structural variant discovery in cancer genomics and rare disease studies
• Epigenetic mapping where base modifications (e.g., 5mC, 6mA) must remain chemically unaltered
• Reference genome improvement and telomere-to-telomere (T2T) assembly projects

FAQ

What distinguishes Megaruptor®3 from ultrasonic shearing instruments like Bioruptor®?
Megaruptor®3 uses deterministic microfluidic shear forces rather than acoustic cavitation, eliminating heat-induced DNA damage, sequence bias, and batch-to-batch variability inherent in probe-based sonicators.
Can Megaruptor®3 process FFPE-derived DNA?
Yes—it reliably fragments partially degraded FFPE DNA while maintaining fragment size control within the 5–30 kb range, suitable for hybrid-capture long-read workflows.
Is cross-contamination possible between runs?
No. The system uses disposable, single-use fluidic cartridges and sealed tube handling—no shared wetted surfaces exist between samples.
Does the instrument require regular recalibration?
No. The microfluidic chip geometry and pressure control system are factory-calibrated and stable over >10,000 cycles; no user recalibration is needed.
How is fragment size verified post-shearing?
Diagenode recommends pulsed-field gel electrophoresis (PFGE) or Femto Pulse analysis for sizing validation; the system’s output is optimized for direct compatibility with Qubit HS and TapeStation Genomic DNA assays.
