Tanon VE-580 Vertical Electrophoresis Cell

Overview

The Tanon VE-580 Vertical Electrophoresis Cell is an engineered platform for high-fidelity polyacrylamide gel electrophoresis (PAGE) of nucleic acids and proteins under controlled, reproducible conditions. It operates on the principle of electrophoretic mobility separation—where charged biomolecules migrate through a porous polyacrylamide matrix under the influence of a uniform electric field—enabling resolution based on molecular weight, conformation, and charge density. Unlike integrated casting-electrophoresis systems, the VE-580 decouples gel preparation from electrophoretic run phases via physically distinct casting frames and electrophoresis chambers. This modular architecture minimizes cross-contamination risk, extends component service life, and supports parallel workflow optimization in academic core facilities, QC laboratories, and biopharmaceutical process development environments.

Key Features

• Modular dual-function design: Independent gel casting frame and electrophoresis chamber ensure operational isolation between gel polymerization and electrophoretic separation.
• High-voltage compatibility: Rated for continuous operation up to 250 V DC, enabling rapid migration without band distortion or thermal gradient-induced smearing.
• Optimized thermal management: Micro-V groove side ventilation channels promote laminar air convection across the gel surface, reducing localized Joule heating and improving band sharpness.
• Dual isolated power circuits: Electrically segregated electrode pathways allow simultaneous or staggered runs across two independent gel sets—critical for comparative experiments or internal reference controls.
• Scratch-resistant glass assembly: Borosilicate glass plates undergo surface-hardening treatment to withstand repeated handling, comb insertion/removal, and chemical exposure during SDS-PAGE or native PAGE protocols.
• Visualized chamber segmentation: Patented butterfly-shaped base with raised inter-gel ridges provides real-time visual confirmation of buffer level uniformity and gel alignment integrity.

Sample Compatibility & Compliance

The VE-580 accommodates standard vertical slab gels (8.6 × 8 cm active area) cast within reusable 10 × 10 cm frames. It supports both hand-poured and pre-cast polyacrylamide gels—including gradient, Tris-Glycine, Bis-Tris, and low-fluorescence formulations—without modification. The system is routinely deployed in applications requiring adherence to analytical method validation frameworks per ICH Q5B, USP <621>, and ISO 13485 Annex A. Its mechanical stability, consistent electrode geometry, and absence of metal-to-gel contact surfaces contribute to inter-run reproducibility essential for regulatory submissions. While not certified as medical device hardware, its construction and traceable material sourcing align with GLP-compliant instrument qualification protocols (IQ/OQ/PQ).

Software & Data Management

The VE-580 is a hardware-only electrophoresis cell and does not incorporate embedded firmware or onboard software. However, it integrates seamlessly with Tanon’s EPS-series power supplies (EPS-1500, EPS-200, EPS-300, EPS-600), all of which support USB/RS-232 interfaces and comply with FDA 21 CFR Part 11 requirements for electronic records and signatures when paired with validated LIMS or ELN platforms. Experimental parameters—including voltage, current, time, and temperature logs—are captured externally via connected power supply units and archived in audit-trail-enabled databases. The system’s mechanical consistency reduces variability sources that would otherwise require extensive post-acquisition normalization in downstream image analysis.

Applications

• SDS-PAGE and native PAGE for protein subunit analysis, purity assessment, and molecular weight estimation.
• Western blotting sample preparation with optimized transfer compatibility using the companion VE-586PRO transfer unit.
• Nucleic acid fragment analysis (e.g., PCR product verification, restriction digest profiling) using high-percentage acrylamide gels.
• Post-translational modification screening via Phos-tag™ or Zn²⁺-based gels requiring precise voltage control and thermal homogeneity.
• Method development for CE-SDS and capillary electrophoresis validation studies where slab-gel benchmarks are required.

FAQ

Can the VE-580 be used with pre-cast gels from third-party vendors?
Yes—the chamber dimensions and electrode spacing conform to industry-standard vertical electrophoresis footprints, ensuring mechanical compatibility with most commercially available pre-cast gels rated for 10 × 10 cm formats.
Is cooling water circulation supported?
No—the VE-580 relies on passive convective cooling; active recirculating chillers are not integrated nor recommended due to its optimized V-groove venting architecture.
What safety certifications does the unit carry?
The VE-580 complies with GB/T 14710-2009 (Chinese environmental testing standards for laboratory equipment) and meets CE marking requirements for low-voltage directive (2014/35/EU) when operated with Tanon-certified power supplies.
How often should the glass plates be replaced?
Under routine use with proper cleaning (e.g., 70% ethanol, followed by deionized water rinse and lint-free drying), borosilicate plates typically maintain optical and dimensional integrity for ≥500 runs; visual inspection for micro-scratches or clouding is recommended prior to critical assays.
Does Tanon provide IQ/OQ documentation templates?
Yes—validated installation and operational qualification templates aligned with ISO/IEC 17025 and ASTM E2500-18 are available upon request for qualified institutional purchasers.
