LY DYCZ-24DH Dual-Plate Vertical Electrophoresis Apparatus

Overview

The LY DYCZ-24DH Dual-Plate Vertical Electrophoresis Apparatus is an engineered solution for high-fidelity SDS-PAGE and native PAGE applications in molecular biology, proteomics, and quality control laboratories. Designed according to standard vertical slab gel electrophoresis principles—based on the migration of charged biomolecules under a constant electric field through a polyacrylamide matrix—the system supports reproducible protein separation across two parallel gels simultaneously. Its architecture integrates electrophoretic chamber functionality with in-situ gel casting, eliminating the need for external casting frames or alignment jigs. This configuration ensures consistent gel thickness, uniform polymerization, and minimal buffer leakage—critical factors affecting band resolution, lane integrity, and inter-gel comparability. The apparatus complies with fundamental design conventions outlined in ISO 13485–aligned laboratory equipment guidelines and supports workflows aligned with GLP-compliant documentation practices when paired with validated protocols.

Key Features

• V-shaped base slope with dual lateral gas-escape channels—engineered to facilitate rapid removal of electrolysis-generated bubbles during electrophoresis, preventing band distortion and current instability.
• Integrated casting–electrophoresis platform: no crossbar obstructing access; enables direct comb insertion, sample loading, and post-run gel extraction without disassembly.
• Reinforced glass assembly: concave plates feature permanently bonded borosilicate edge strips, increasing mechanical rigidity and minimizing fracture risk during gel handling or pressure-induced sealing.
• U-shaped molded silicone gasket seated within a precision-machined U-groove on the main body—combined with angled insertion plates—to achieve consistent compression sealing across both gel chambers.
• Eccentric cam-lock gel former with top-mounted alignment boss: ensures precise registration between glass plates and dual sealing gaskets, reducing gel leakage during polymerization and electrophoresis.
• Interchangeable comb system compatible with DYCZ-24DN accessories—supporting method transfer and instrument fleet standardization across core facilities.
• High-conductivity platinum wire electrodes: low-resistance current path minimizes joule heating and improves run-to-run voltage stability.
• Automatic power cutoff upon lid opening—meets IEC 61010-1 safety requirements for Class I laboratory electrical equipment.

Sample Compatibility & Compliance

The DYCZ-24DH accommodates standard polyacrylamide gel formulations (e.g., 8–20% T, 2.6% C) and common running buffers including Tris-Glycine, Tris-Tricine, and Bis-Tris MES systems. It supports both pre-cast and hand-poured gels, with compatibility extending to gradient gels and zymogram substrates when used with appropriate casting protocols. All wetted components—including glass plates, silicone gaskets, and buffer chambers—are chemically resistant to acrylamide monomers, TEMED, ammonium persulfate, and common denaturants (e.g., urea, SDS). The system does not incorporate electronic controllers or data logging hardware; therefore, it operates outside FDA 21 CFR Part 11 scope but remains suitable for use in ISO/IEC 17025-accredited testing laboratories where manual protocol execution and paper-based recordkeeping are employed.

Software & Data Management

As a standalone electrophoresis apparatus without embedded microprocessors or digital interfaces, the DYCZ-24DH does not include proprietary software or firmware. Data acquisition and analysis are performed externally using third-party imaging systems (e.g., ChemiDoc MP, Azure c600) and quantification platforms (ImageLab, Quantity One, or open-source tools such as Fiji/ImageJ). Users retain full control over image capture parameters, lane profiling, molecular weight calibration, and densitometric normalization—enabling audit-ready traceability when raw images and processing logs are archived per institutional SOPs. The mechanical consistency of gel dimensions and buffer volume (400 mL total) contributes to inter-run repeatability essential for semi-quantitative comparative studies.

Applications

• SDS-PAGE analysis of purified recombinant proteins, cell lysates, and immunoprecipitated complexes.
• Western blotting workflow support—optimized for transfer efficiency due to uniform gel thickness (1.0 mm and 1.5 mm standard options).
• Native PAGE for oligomeric state assessment of enzymes and membrane protein complexes.
• Two-dimensional electrophoresis first-dimension compatibility (IEF strips placed directly onto cast gels).
• Educational laboratory instruction in biochemistry and molecular genetics—robust construction and intuitive operation support high-throughput student training.
• QC release testing of biopharmaceutical intermediates where visual band pattern conformity is required per USP or EP 2.6.27.

FAQ

Is the DYCZ-24DH compatible with standard electrophoresis power supplies?
Yes—it accepts standard DC output power supplies (typically 0–300 V, 0–400 mA) via its integrated electrode terminals and conforms to universal banana-jack connectivity.
Can I use 0.75 mm gels for high-resolution separation of small peptides?
Yes—0.75 mm thickness combs and corresponding glass spacers are available as optional accessories and are routinely applied in low-MW peptide electrophoresis.
Does the system support gradient gels?
Yes—its sealed dual-chamber design and stable plate alignment allow reliable pouring of continuous or discontinuous acrylamide gradients using standard gradient mixers.
Are replacement parts such as gaskets and combs available separately?
Yes—all consumables—including U-gaskets, combs (10-/15-well, multiple thicknesses), glass plates, and gel formers—are cataloged under LY’s spare parts numbering system and distributed globally through authorized channels.
What maintenance is required to ensure long-term performance?
Routine cleaning with deionized water and mild detergent after each use; periodic inspection of platinum electrodes for pitting or sulfide deposition; storage with desiccant to prevent silicone gasket degradation.
