Agilent 4150 TapeStation Automated Electrophoresis System

Overview

The Agilent 4150 TapeStation Automated Electrophoresis System is a compact, entry-level platform engineered for high-reproducibility nucleic acid quality control (QC) in low-to-moderate throughput laboratory environments. It implements Agilent’s proprietary ScreenTape technology—a microfluidic, capillary-based electrophoretic separation method that replaces traditional slab-gel electrophoresis with pre-cast, single-use tape cartridges containing 16 independent electrophoretic lanes. Unlike conventional agarose or polyacrylamide gels, ScreenTape devices integrate sample loading wells, separation matrix, and detection zones into a sealed, disposable format—eliminating manual gel pouring, staining, destaining, and imaging steps. The system operates on the principle of size-based separation under controlled electric field conditions, followed by real-time fluorescent detection using integrated LED excitation and CCD-based imaging. This architecture delivers quantitative assessment of DNA and RNA integrity, concentration, and molecular weight distribution in under two minutes per sample, with full 16-sample runs completed within 20 minutes. Designed specifically for QC applications in next-generation sequencing (NGS) library preparation, biobanking, mRNA vaccine development, and diagnostic assay validation, the 4150 TapeStation provides traceable, standardized metrics—including RNA Integrity Number equivalent (RINe), DNA Integrity Number (DIN), and circulating free DNA percentage (%cfDNA)—all compliant with internal QC benchmarks used across regulated genomics workflows.

Key Features

• Automated, walk-away operation with minimal hands-on time: Load samples and ScreenTape cartridges, then initiate run via intuitive touchscreen interface.
• ScreenTape consumables—pre-formulated for DNA or RNA analysis—require no buffer preparation, gel casting, or post-run staining; each lane is physically isolated, eliminating cross-contamination risk.
• Scalable sample processing: Supports 1–16 samples per run without protocol adjustment or reconfiguration—ideal for labs with variable daily throughput requirements.
• Ultra-low sample consumption: Analyzes as little as 1–2 µL of total RNA or genomic DNA, preserving precious clinical or limited-yield samples.
• Compact footprint (254 × 510 × 417 mm) optimized for benchtop integration in space-constrained core facilities or GMP-compliant QC labs.
• Self-diagnostics and guided maintenance routines reduce downtime; firmware updates and calibration checks are performed locally without service engineer intervention.
• ACT (Accountability, Consistency, Transparency) certified by My Green Lab—validated for reduced environmental impact across manufacturing, energy use, and end-of-life recyclability.

Sample Compatibility & Compliance

The 4150 TapeStation supports all Agilent ScreenTape assays, including but not limited to Genomic DNA, High Sensitivity DNA, RNA ScreenTape, and cfDNA ScreenTape kits. It accommodates diverse nucleic acid sources—FFPE-derived RNA, plasma-isolated cfDNA, in vitro transcribed mRNA, and enzymatically sheared NGS libraries—without modification to hardware or software. All reported metrics (RINe, DIN, %cfDNA) are derived from algorithmically normalized electropherogram profiles and validated against reference standards defined in Agilent’s technical documentation. While not a Class I medical device, the system meets general laboratory equipment safety standards (IEC 61010-1) and electromagnetic compatibility (EMC) requirements per EN 61326-1. Data outputs comply with ALCOA+ principles when used in conjunction with Agilent’s optional secure software licensing and audit trail configuration—supporting GLP/GMP-aligned documentation practices where required.

Software & Data Management

Instrument control, data acquisition, and report generation are managed through Agilent TapeStation Software (v6.x or later), installed locally on Windows-based PCs. The software features role-based user access control, electronic signature capability (when configured with appropriate security settings), and export options for CSV, PDF, and XML formats. Raw electropherograms, lane-by-lane quantification tables, and QC pass/fail flags are stored with embedded metadata—including date/time stamp, operator ID, assay type, and cartridge lot number. Audit trails record all user-initiated actions (e.g., method edits, result overrides, calibration events) in tamper-evident log files. For laboratories operating under FDA 21 CFR Part 11 requirements, optional software modules enable electronic signature enforcement, automated backup, and long-term archival compliance—though full Part 11 validation remains the responsibility of the end-user’s IT and QA departments.

Applications

• Pre-sequencing QC of fragmented DNA and cDNA libraries prior to Illumina, PacBio, or Oxford Nanopore sequencing.
• Routine integrity assessment of RNA extracted from clinical biopsies, PBMCs, or cell culture—particularly critical for mRNA vaccine stability monitoring.
• Quantitative evaluation of cfDNA fragment size distribution in liquid biopsy workflows.
• Batch release testing of plasmid DNA preparations used in viral vector manufacturing.
• Verification of ribosomal RNA depletion efficiency in RNA-seq sample prep pipelines.
• Supporting ISO/IEC 17025-accredited testing laboratories requiring documented repeatability and inter-instrument comparability (via cross-platform alignment with 4200 TapeStation systems).

FAQ

Can the 4150 TapeStation be upgraded to support higher throughput?
Yes—the 4150 shares identical assay chemistry and software architecture with the 4200 TapeStation; migration requires only instrument replacement and license transfer, preserving method files and historical data compatibility.
Is ScreenTape reuse permitted?
No. Each ScreenTape cartridge is designed for single-use only. Partial use does not extend cartridge lifetime, and re-use violates assay performance specifications and voids QC metric validity.
Does the system require external cooling or ventilation?
No. The instrument operates passively cooled and meets Class A emission limits for laboratory environments; no dedicated exhaust or air conditioning is needed.
How is data integrity ensured during power interruption?
All active runs write intermediate data to non-volatile memory at 10-second intervals; upon recovery, the system resumes acquisition from the last saved checkpoint without loss of electropherogram fidelity.
Are third-party ScreenTape alternatives supported?
No. Only Agilent-branded ScreenTape consumables are qualified for use; non-OEM tapes may compromise resolution, reproducibility, and regulatory traceability.
