LY DYCZ-30C Dual-Plate Sandwich-Style Vertical Electrophoresis Apparatus

Overview

The LY DYCZ-30C Dual-Plate Sandwich-Style Vertical Electrophoresis Apparatus is a precision-engineered system designed for high-resolution separation of biomolecules—including proteins, nucleic acids, and complex protein isoforms—via vertical slab gel electrophoresis. It operates on the principle of electrophoretic mobility under controlled DC electric fields, where charged macromolecules migrate through a polyacrylamide or agarose matrix at rates determined by molecular weight, charge density, and conformation. Its defining structural feature—a rigid dual-glass-plate sandwich configuration—ensures uniform gel thickness, minimal buffer leakage, and consistent thermal dissipation across the entire gel surface. This architecture mitigates edge effects and Joule heating-induced band distortion, enabling reproducible isoelectric focusing (IEF), SDS-PAGE, native PAGE, and two-dimensional electrophoresis (2D-PAGE) workflows. The apparatus complies with standard laboratory safety and electrical safety requirements for Class I equipment per IEC 61010-1, and its mechanical design supports routine use in GLP-compliant academic, clinical diagnostic, and QC/QA laboratories.

Key Features

• Dual-plate clamping mechanism with precision-machined stainless-steel frame ensures parallel alignment of glass plates within ±0.05 mm tolerance, critical for uniform polymerization and electrophoretic resolution.
• Integrated buffer chamber with 1750 mL total capacity provides stable ionic strength and pH buffering during extended runs (up to 8 hours at 200 V), minimizing pH drift and current fluctuation.
• Modular comb and spacer system accommodates multiple gel thicknesses (1.0 mm and 1.5 mm) and well geometries (25-, 40-, and 52-well formats), supporting diverse sample throughput and loading volume requirements (0.5–20 µL per lane).
• Vertical orientation enables straightforward gel casting, sample loading, and post-run handling—reducing procedural variability associated with horizontal systems.
• Corrosion-resistant electrode assembly (platinum-coated titanium anode/cathode) ensures long-term stability and low background electrolysis, compatible with common electrophoresis buffers (Tris-Glycine, Tris-Tricine, and IPG buffer systems).
• Compact footprint (250 × 160 × 158 mm) and lightweight construction (1.7 kg) facilitate benchtop deployment in space-constrained environments without compromising mechanical rigidity.

Sample Compatibility & Compliance

The DYCZ-30C supports standard polyacrylamide gels (4–20% T, 2.6–6% C), gradient gels, and agarose-polyacrylamide hybrid matrices. It is routinely employed in applications requiring compliance with ISO/IEC 17025 analytical method validation guidelines, including seed purity testing per ISTA protocols and protein identity verification per USP . The system is compatible with downstream transfer techniques (wet and semi-dry blotting) and UV/visible staining methods (Coomassie Brilliant Blue R-250, silver nitrate, SYPRO Ruby). All supplied glass plates and spacers meet ASTM D1003 optical clarity standards, ensuring compatibility with digital gel documentation systems. No proprietary consumables are required; third-party combs, gels, and buffers conforming to ISO 9001-certified manufacturing practices may be used interchangeably.

Software & Data Management

As a standalone electrophoresis apparatus, the DYCZ-30C does not include embedded firmware or onboard software. It is fully compatible with external power supplies featuring programmable voltage/current ramping (e.g., Bio-Rad PowerPac HC, Thermo Fisher Ettan Power Supply), which support time-stamped run logging and exportable CSV data files. When integrated into validated workflows, it supports audit-trail generation via connected laboratory information management systems (LIMS) that comply with FDA 21 CFR Part 11 requirements for electronic records and signatures—provided the power supply and imaging system meet applicable security and traceability criteria.

Applications

• Protein characterization: SDS-PAGE for molecular weight estimation, native PAGE for oligomeric state analysis, and IEF for pI determination in monoclonal antibody development and biosimilar comparability studies.
• Agricultural biotechnology: Seed varietal purity assessment per national regulatory frameworks (e.g., USDA-APHIS, EU Regulation (EC) No 809/2004) using esterase or peroxidase zymogram profiles.
• Clinical diagnostics: Hemoglobin variant screening (HbA, HbS, HbC) and serum protein electrophoresis (SPEP) in resource-limited settings where robustness and low maintenance are essential.
• Quality control: Routine lot-release testing of recombinant enzymes and purified antigens in accordance with ICH Q5B and Q5C guidelines.
• Academic research: Teaching laboratories conducting foundational electrophoresis experiments aligned with ASM and ASBMB curriculum standards.

FAQ

Is the DYCZ-30C compatible with pre-cast gels?
No—it is designed exclusively for hand-cast slab gels using the supplied glass plates, spacers, and combs.
What power supply specifications are recommended?
A constant-voltage or constant-current supply capable of delivering 10–500 V and 10–500 mA, with overcurrent protection and ripple <2%, is required.
Can the apparatus be used for electroelution or in-gel digestion?
Yes—the open-top chamber design and removable glass plates allow direct access to excised gel bands for downstream processing.
Are replacement parts available internationally?
Yes—LY-certified spare parts (glass plates, combs, frames) are distributed globally through authorized partners with documented traceability and material certifications.
Does the system support temperature-controlled electrophoresis?
No built-in cooling is provided; however, the high thermal mass of the glass plates and large buffer volume enable stable operation at ambient temperatures up to 25°C. For higher-voltage runs, external recirculating chillers may be interfaced via inlet/outlet ports.
