Overview
The Junyi JY-SCZ7 Vertical Electrophoresis Tank is an engineered platform designed for high-resolution isoelectric focusing (IEF) and standard vertical polyacrylamide gel electrophoresis (PAGE), primarily deployed in seed purity testing, protein characterization, and nucleic acid analysis within academic, agricultural, and quality control laboratories. Its design adheres to the physical principles of electrophoretic mobility under a stable, uniform electric field—minimizing edge effects through optimized electrode geometry and chamber insulation. The tank supports slab gels cast between two glass plates (278 × 170 mm plate size), accommodating active gel areas of 235 × 145 mm with precise 1.0 mm thickness control—critical for reproducible IEF pH gradient formation and sharp band resolution. Constructed from durable, UV-resistant acrylic and corrosion-resistant stainless-steel electrodes, the system ensures long-term dimensional stability and electrical integrity across repeated thermal and chemical exposure cycles.
Key Features
- Edge-field suppression architecture: Precision-machined buffer chambers and electrode alignment eliminate lateral current dispersion, resulting in straight, undistorted electrophoretic bands—validated in peer-reviewed seed certification protocols published in Seed World.
- Safety-integrated lid mechanism: A dedicated mechanical release button enables one-handed lid opening; concurrent microswitch activation cuts power to electrodes upon lid lift—compliant with IEC 61010-1 safety requirements for laboratory electrical equipment.
- Modular electrode assembly: Removable stainless-steel electrode holders allow rapid cleaning, calibration verification, or replacement without disassembling the main tank body—reducing downtime during routine maintenance.
- Dual-mode gel compatibility: Supports both hand-cast gels (using optional gel-casting comb and sealing strips) and pre-cast gel insertion—enabling workflow flexibility across research and high-throughput screening environments.
- Thermally stable buffer reservoir: 1800 mL capacity maintains consistent conductivity and temperature distribution during extended runs (e.g., overnight IEF), minimizing pH drift and improving inter-run reproducibility.
Sample Compatibility & Compliance
The JY-SCZ7 accommodates standard SDS-PAGE, native PAGE, and IEF gels (pH 3–10 or narrow-range immobilized pH gradients) for proteins up to 200 kDa and nucleic acids ranging from 50 bp to 10 kb. It is routinely employed in ISO/IEC 17025-accredited seed testing labs for varietal identification per ISTA Rule 5B (Electrophoretic Analysis of Seed Proteins). While not certified to GLP or FDA 21 CFR Part 11 out-of-the-box, its mechanical design and operational repeatability support audit-ready documentation when integrated into validated SOPs—including traceable voltage/current logging via external power supplies meeting EN 61326-1 electromagnetic compatibility standards.
Software & Data Management
As a standalone electrophoresis tank, the JY-SCZ7 does not incorporate embedded electronics or proprietary software. It functions as a passive, hardware-only module compatible with all industry-standard DC power supplies (e.g., Bio-Rad PowerPac, Thermo Fisher Owl E3) and imaging systems (e.g., Azure Sapphire, UVP ChemStudio). Users retain full control over run parameters—including voltage ramping profiles, constant-current modes, and timed termination—via their selected power supply interface. Raw gel data (stained or fluorescent) is captured externally and processed using open-format tools such as ImageJ, AlphaView SA, or commercial packages compliant with ISO/IEC 17025 data integrity requirements.
Applications
- Seed varietal purity assessment in agricultural certification labs, per national regulatory frameworks (e.g., China’s NY/T 1437–2007, EU Regulation No. 808/2013).
- Protein isoform profiling in plant breeding programs, including storage protein (e.g., gliadin, zein) and enzyme variant separation.
- Quality control of recombinant proteins and monoclonal antibodies during upstream/downstream process development.
- Teaching laboratory use for undergraduate biochemistry courses emphasizing electrophoretic theory, buffer chemistry, and molecular weight estimation.
- Preparative-scale PAGE for downstream extraction of resolved protein bands prior to mass spectrometry or activity assays.
FAQ
Is the JY-SCZ7 compatible with standard electrophoresis power supplies?
Yes—it accepts standard DC outputs (up to 600 V / 500 mA) via banana-jack terminals and requires no proprietary interface.
Can it be used for SDS-PAGE as well as IEF?
Yes—its uniform field geometry and thermal management support both denaturing and non-denaturing vertical electrophoresis applications.
What is the maximum recommended run time for IEF applications?
For optimal pH gradient stability, continuous runs exceeding 12 hours should include active cooling or ambient temperature control below 22 °C.
Are replacement parts (e.g., electrodes, sealing strips) available separately?
Yes—Junyi provides OEM-specified consumables and wear components under part numbers JY-SCZ7-ELEC and JY-SCZ7-SEAL, distributed globally through authorized channels.
Does the system meet CE or RoHS requirements?
The unit complies with RoHS Directive 2011/65/EU for hazardous substances; CE marking applies only when integrated with a CE-certified power supply and used within specified environmental conditions (EN 61010-1).
